Well here is an update.. and your gonna love this !
After a couple of fone calls they agreed that yes, I was in credit to the tune of ?690+ quid and that ( in their words ) this matter will be addressed.
Then I get another fone call..
Mr Smith, you have a prepayment meter.
yup
Well you cannot go into credit with one of those..
Well I obviously can and have done !
Well we do not know how but you cannot have a refund because you cannot be in credit.
But your statement says I am in credit
Yes, we see you have over paid by ?693.20 ( or whatever )
So therefore you owe that money to me..
No Mr Smith, we do not owe it to you as it is not possible to go into a credit situation with a prepayment meter..
ARRRRRRRRGGGGGGGGGGGGGGGGGGGGGGGGGHHHHHHHHHHHHHHHHHHH!!!!!
