I had my accounts at Cater Allen bank closed, without a reason.
Then they proceeded to send me account upgrades.
Then they said they are actually closing them.
Then I got another upgrade, to a "Platinum" account...
In the end I ended up charging me £15 because my account balance was below 5k.... not having realised this was because they closed the account ;)
I now have a wad of paperwork from this outfit, showing that nobody there talks to anybody else.
Even the foreign-name character who signed the first letter cannot spell his job title.
It's quite fun to read, actually.
Whether this is untypical I don't know... I still get statements from Shittybank (Citibank), some 10 years after I closed the account, and some 2 years after they closed it due to a lack of transactions..... I dropped them because they would sometimes not action money transfers, because my name generated a match against a list of known terrorists supplied by the US Govt ;)
