I was a temporary customer for 1 month in my new home until I used uSwitch to change supplier. I gave them my opening readings and closing readings for the final bill and they but they sent me a bill based on random numbers. I have tried to correct this by being in contact with at least 8 different agents and have up until now been issued with 4 final bills. All different and the last one also covering a period in time when I didn't even own the property. I have the readings, give them to agents and they just don't get it right. Tomorrow I have to ring them again and waste another couple of hours.
