I received a bill for £550 from a flat I lived in from oct 2012 - aug 2014.
I paid all my bills via direct debit on time, gave them a last meter reading before closing account on the 15th aug 2013.
I called the company today and they said someone called on the 16th August and gave a different reading which was lower to the one I gave.
Apparently he (LL) started disputing his bills in January this year, which is why I've now received this bill.
They said I need to get in touch with cab as its just our word against his with little evidence. I did that and have an appointment on Monday.
I've googled the energy company and they have similar reviews saying the same thing happened to others. They begin with U and W.
Any advice?
