Hi Guys, I hope your well. I had a mobile phone contract with Vodafone back in 2011 and made regular payments on time never having any issues. Towards the end of the sim only contract Vodafone were contacting me to try and encourage me to upgrade to a new contract along with taking a handset as part of a new contract. I refused to this but when sales rep was discussing my options he said I had never used more than 300 minutes in a month. However maybe a month later I received a bill from Vodafone saying I had exceed my allowances of minutes and I owed them something like £150. I was immediately suspicious of this as had never used anywhere near my allowance of minutes in a month and the vodafone service where you can check your minutes had stated I will still within my allowance. I contacted Vodafone and disputed the charges and asked for an itemized bill listing all of the numbers I was alleged to have rang so I could I could check the charges were valid. I never received any response to my requests and as the contract was due to terminate anyway I took out a contract with another provider and never had any further correspondence from Vodafone. That was till yesterday when I received a letter from Bryan Carter Solicitors on behalf of Fredricksons stating that unless I pay them £202.00 prior to the 09/04/14 they are going to issue court proceedings for an amount of money I don't believe I owe and have never had any sort of bill for. I have also checked my credit file and it shows a default on there from a company called Lowell who have performed numerous unlawful searches on my credit file as well as registering a default in 2013 although the alleged debt related to 2011. I am unsure as to how to deal with this threat from a company I have never heard of and debt I have never had any notification of. I believe there is some kind of prove it letter I can send to Bryan Carter asking them to provide any supporting documentation to go along with any claim they are trying to bring against me. I appreciate the amount of money owed is only small but I have always disputed the charges and never had any bill. I was also completely unaware my credit file was being accessed by a company (lowell portfolio) who I have never had any dealings with. If there any template letters I can send to Bryan Cater solicitors I would very much appreciate it. Any help and advice would be greatly appreciated as I only have till 09/04/14 to decide how I am going to deal with this issue. Thanking you in advance Chris
