Don't get me wrong, I think it's abhorrent, but it's something you should think about.
I once tried to open a new bank account with my bank of 10y, and set up direct debit to it. The point was that I was going to pay my rent from that new account (both me and a roommate would pay into the account, and a direct-debit would go to the landlord).
I filed the paperwork, in person, and heard nothing, a week passed, I phoned the bank, they said call back tomorrow.
I did, "please call in a week".
Waited a week, "please call back next week"..
So I go in person to the bank, and I refuse to leave until they fix it- I was being pressured by the landlord, I couldn't take the keys of the new property until proof of direct debit was handed over.
I waited for 5hrs in the lobby, basically from a few minutes after the branch opened until the mid-afternoon. Eventually a teller decided to help me because none of the bank managers were going to look at it.
What was the problem? apparently because I had claimed to have an income on one of the forms they wanted proof. I had never been asked to delclare proof before; and bearing in mind that previously I had never declared any income on any account _and_ I had standing orders/direct debits coming from the account; this was also the account that was where my salary landed, the only account I'd had since I was 13.
I tried to give proof, I showed bank statements and payslips... contracts etc; but because the payslips were on my phone they didn't accept them, I asked if I could use a printer and they said no.
So, I walked across the street to Barclays, opened 3 accounts with my passport and a proof-of-address, set up all my direct debits in 1hr, transferred all my money and that was the end of it.
What pissed me off most was the lack of transparency on exactly /why/ they decided not to move forward, expecting me to just sit on my hands forever is not good.
Fuck you HSBC, that was nearly 10 years ago and I still fucking hate you.
er... my point is that corps can be fickle and you shouldn't trust any of them. Especially the ones that implore you to trust them.
