its normal with banking. Luckily its only 6 months.
I know of a country which is very famous for banking and many folks here have accounts in (including me) where money can be held for 10 years counting or whose banks apply other sneaky methods to screw you (more or less legally).
Yes, banks usually are eager to act even in light of the smallest potential problem because many got fined for lack of proper AML measures quite heavily
I tried them for a few months but then gave up.︈ zero support, low rates, no real product, and they only call when they need to︉ sell something. One more "bank" to stay away from.
