Hi folks. First post here, as there was a similar thread to mine, but no follow up to it. I received a letter from Past Due Credit Solutions regarding an old gas bill (about 4 years old) from a property I used to live at. I sent off the prove it letter, and today received a response saying the account would be placed on hold for 28 days etc. They have asked me: We would ask if you can confirm the following: (for data protection) The connection you have to the above supply address (previous address) Before I moved into the property, I switched from my current supplier so they could take over the new house. So, instead of British Gas, it was E:On I was paying my bills to, but BG didn't seem to be aware of this. BG have issued a default on my credit file because of this, and obviously I would like to get it removed. Will Past Due be able to get the default removed, or will I have to contact BG? Also, what response should I send over to PDCS? Thanks in advance
