Good to find your forum - it has given me the impetus to carry on the fight.
I'll not bore you with too many details but last October we got into serious financial difficulties. We have since re-mortgaged our house (which I told the Halifax was our intention) but we have been charged over £900 for what was, in effect, 19 days of being over authorised overdraft limit ( and never more than £488 - our cheques go in the bank at odd intervals making it very difficult to know if you are within your limit).
What I find so deplorable is that a) no-one phones you to discuss your situation - even though you have banked with them for 20 years and b) even worse, several times my debit card was accepted at a supermarket - once for just £7.96 - and 2 days later I had a letter saying that I would be charged £30 for this. Sometimes my card would be accepted and other times it would be declined in the supermarket - so no consistency. If they'd just declined these small payments I could have used a credit card instead!
It is also well worth scouring through your statements. Being in a dire financial state I'd become a bit of an ostrich and didn't look through everything thoroughly and have since discovered some of these charges were imposed even though, according to our statements, we were within our authorised limit. Let that be a lesson to everyone - and KEEP EVERYTHING.
Have just sent off my 2nd letter to the bank from one of your proformas (my first, detailed, letter elicited a response of "we will refund you the £28 overdraft fee"!)
thanks again for your very useful forum and so much for "I won't bore you with the details"!!!!!
