O.k, I live in a flat share with one other person. Up until last year we were happy with our electricity supplier, until, in March out of the blue we received a letter from them containing a final bill and cancellation fee. I called them and queried it and they assured me it was just an error and they'd sort it out! However, a week later we received another letter. This time from 'Spark energy' who claimed, that 'since this was an empty property they had taken over the electricity'. At this point I had no idea who spark energy were. I called my original provider and asked to be transferred back and called spark energy within their extraordinarily short deadline period to confirm we would be switching back from them. They said it was fine, they had none of our details anyway, it would go through without a problem. The next week we received a letter, again from our original provider stating that spark had denied the transfer, with no indication as to why! I called my original provider and stated that since I had not expressed my permission for the switch or had any prior dealings with spark energy I did not feel comfortable dealing with them and under no circumstances did I want them to have access to any of my details. They said they would send a letter to spark requesting they transferred us back over and that they would send me a copy.
I heard nothing from them after that, other than from debt collectors mithering for the final bill payment. I explained the situation and they said they'd get in touch with the providers and they would on turn be in touch with me. This was December.
Since then I have tried to garner some sense out of citizens advice e.t.c with the growing concern that this would be a very expensive and lengthy problem. No one was able to advise me properly.
I haven't heard anything at all from Spark or my original provider since they hijacked our account. Until today, we received a letter from Spark demanding we pay £2,500 by the 11th of this month (that's right 3 days from now.) This letter is addressed to 'the tenant'.
