I thought I had already posted this but I can't find it - so here it is again.
BDC have invoiced me for 204.47 euros. They have admitted in an extranet message that this amount is wrong. They have agreed that I only owe 109.07. I really would like to pay what I owe but BDC will not amend the account. I do not trust them not to ask for the difference if I pay the lower amount unless they amend the invoice.
This has been going on for months. The helpline agree that we only owe the lower amount and all I get from accounts is how to pay.
