Absolute joke of a company ... I thought British Gas were bad but they employ these jokers to chase money that's already been paid. I've sent them proof 4 times that there is no outstanding amount and all they can say is they haven't read the email yet even though I've had confirmation of them receiving it.

UPDATE.
A month after this review and they are still ringing me. They have the proof it's been paid but failed to read the notes prior to ringing me.
I hope some of you idiots who work there read this.
Once again I was promised they would sort it
(the previous 3 idiots I spoke to promised me the same)
Another hour of my day wasted on these jokers.
They take incompetence to a whole new level.
