Scottish Debt Any One Get A Big Bill As Well As Being On A Key Meter With Scottish Power?

Any one get a big bill as well as being on a key meter with scottish power? - scottish debt

I moved 6 months ago and I just had a call from the company called to say that Levi must have black £ 350 to Scottish Power as my key meter (ELE) was collected for 4 years because no tarrif changed. I was so shocked that someone else would have simillar problem. I believe that it is the task of amending the tarrif, why should I pay. After all, we had an important first meter, so you still have not received debt ..... I am now debt of £ 350 ....
