Horrendous customer service! After 7 month of being supplied electricity only by this company and having no problems whatsoever, I moved house and left their supply. I gave a final meter reading on that day I left the property and had to chase this for the final bill. Eventually I was sent a bill, showing, as I believed, that I was in credit. When asking for the credit back I was told I actually owed £176! A new bill had been created for the entire previous 7 months, despite me paying these monthly with a meter reading. It has now been 4 months and I am being harassed by them to pay up whilst also being told by staff that they know I don't owe anything. I have now written 3 complaints, all of which are not even allocated to anyone by their 10 working day deadline. Each time someone promises to call me or cancel the erroneous bill, but they do not. I have had to go externally to Resolver to help me. I cannot begin to describe the stress and wasted hours over this.
