Didn't want to say but we have just come out of the other end of MAJOR issues with pg..Aftre 4 years of disputing paying £5 a month for gas they finally found out that they had f*cked up big time..4 weeks ago we had a gas bill for £2500..!!! .
I have fought them to the end and yesterday they told me I owe the grand total of £0..! Their error so they wiped my debt.
BUT that said, I think most companies have major issues at one time or another..again it's all down to the individual.
