Ian2012 - I have now heard from T-Mobile through the Executive Office email 'We wrote to our customers between 02 April and 08 April 2013 informing them of the changes to their price plan charge. In accordance with our terms and conditions, the relevant measure of RPI should therefore reflect the period 1 April 2012 to 31 March 2013. The Office of National Statistics published its official rate of RPI for this period in April. The official measure of RPI for this period is 3.3%. This is in line with the 3.3% price increase that will take effect from 10th May. Therefore due to this you are unable to end the term of your agreement without penalty. Please be assured our customer's views are important to us and your comments are fully acknowledged. Yours sincerely Executive Office, EE' Now concidering my next move

I read with interest your postings earlier I'm a pre-October contract

Update - Not hearing anything from T-Mobile called today. told them I had called, written and emailed T Mobile on a number of occasions and had no response so wanted to find out the current situation. Was on hold for about 5 mins and came back to tell me that T Mobile legal are still looking into it. However they had reviewed my contract and could offer more minutes and more text etc for the original price of the monthly contract without the rise. I refused and stated I will wait until I eventually hear from T Mobile customer complaints. They obviously concerned enough to make such offers

So by the time they sent you the letter on April 18 they could quote the ONS RPI, but you were not in a position to know that and it is interesting then that the letter we received April could not reflect the ONS RPI released on March 19th?? That's rubbish surely as it does not give a clear 30 days from the notification of the increase until its applied to the May bill for customers to cancel because they don't know that the RPI is going to change half way through the process then becomes applicable. Basically what they are saying is here a letter telling you of an increase and by the way its not based on the rise in the RPI that you can check on its based on the RPI yet to be release that you don't yet know about WTH!!! In every conversation I have had they have stated that the rate used in the letter was the one published in February and therefore in my option it is that rate published in March I will continue to peruse.

Based on the information kindly posted on the forums.moneysavingexpert.com/showpost.php?p=60738119&postcount=159 I contacted TMobile on 01707-315000 and asked to speak to Mr Swantee and was also put through to the Executive office. I explained the situation to the lady who took my details then said 'at the moment as our legal team is looking into this and I cannot give you an indication of when that will be completed but I will get back to you'. me: 'will the legal dept responded if I call next week at this time' lady: 'I don't know' me: 'Can I provide my email address so you can email when there is a response?' lady: 'Yes' In the meantime I have also sent a letter recorded delivery to TMobiles complaints which has been sign for.

In the many conversations I have had the person has always quoted that the rate used was the one released in February which was 3.3%

They haven't replied.

I have posted on TMobiles Facebook pages detailing the situation - The most recent reply is: The increase in the price plan charges is in line with the 3.3% rate of inflation as measured by the Retail Price Index (RPI) released on 12 February 2013. Our pay monthly terms and conditions state that we may increase charges by up to the RPI figure in any 12 month period. I have responded: It is irrelevant what the Retail Price Index (RPI) released on 12 February 2013 was as the notification I received of an increase in my plan was not in March. What is relevant is the Retail Price Index (RPI) released on 19 March 2013 as the notification I received was in April and dated April which means the increase in my plan for the previous 12 month prior to the notification date in April is above the RPI of 3.2% release in March. Your term state 7.1.4 is an increase in Your Price Plan Charge (as a percentage) higher than any increase in the Retail Price Index (also calculated as a percentage) for the 12 months before the month in which We send You Written Notice and You give Us notice to immediately cancel this Agreement before the change takes effect. I am now waiting for their response
