Thanks for the replies guys. I've worked it out and realised that the amount owed is infact the remainder of my bill. Stupid of me not to realise but nevermind, now I know. I've just sent a 'prove it' letter to DLC, just waiting to hear back. I was just wondering if there are any letter templates that let them know I can only afford to pay £5 a month to them as I have little to no disposable income. Thanks for the help already!

Hello, I received a letter from Orange on the 6th Feb 2011 demanding full payment of £170.81 which I owe or risk debt collection. I replied in letter and stated that I had currently lost my job and can only afford to pay them £5 a month. They didn't reply. Then I've just (23/02/11) received a letter from DLC demanding £862.24 on behalf of Orange. How can this be right? These are some crazy charges, they don't give any information on what they are for or my original debt. The letter is all jumbled up too, words over other words and I can only just make out that its on behalf of Orange. Any advice would be much appreciated! Im a total newby to this sort of stuff and have no legal knowledge at all. Thanks guys.
