I have been with around 8 suppliers now for gas and electricity. All have been fair though switching regularly to get better deals. All has gone well until trying to leave npower through uswitch. I have never met such a poor set up not tailored the customers needs. I switched in April and was given a refund in early May of £69 made directly to my bank. Fantastic! Time to spend! 10 September I receive an email telling me I owe them £54!!! Why? I complained and asked for an explanation in writing and how I could repay over time. I got a letter saying by agreement with me the complaint had been closed. Untrue. No mention of a way to make affordable payments! I complained by phone - they wanted me to give them card details - I wanted to pay with some post dated cheques so I could keep account... no we can't do that. While I was on the phone (30mins plus - kept me waiting) the post arrived - dated two days after my complaint had been closed by them (without n my agreement) a letter demanding payment or my credit rating would be compromised! Poor, poor and worse than poor. I only gave a one star because it isn't possible to give less.
