> Don’t bank with HSBC. After having similarly-frustrating things happen with my HSBC personal accounts over the years, I fully support this suggestion. They are awful. They take extreme steps (suspending accounts, rejecting payments, etc.) without contacting the customer; when you reach out to them, it's hours of being passed around before you reach the right person. If you reach a person at all.
He reported it and they suspended his account immediately while they investigated, which is fine. What wasn't fine was it took them well over a month to investigate, in the mean time all of his money was locked up tight and he was unable to access it, pay rent, buy lunch etc (we ended up shouting him for meals for a bit to help out until work organised an advance on his salary). In the end he really regretted 1) having all his money in a single account, and 2) ever having bothered telling HSBC about the transfer.
