I agree with a previous reviewer, this group are beyond inept. I have spent hours on the phone sorting my business bills with the company, wanting to pay them for historic energy use but with them unable to confirm basic details. I then had it in mind that we had worked to close the account with all bills settled, only to be issued a credit. A few months later a further credit was issued, when i called to claim it they couldn't pass me through security because the value of payments didn't match their records, I was working directly from accounts payable data?!?
