Unfortunately, not always. I had once my account frozen by one of the UK's largest banks for days. The reason? Apparently they didn't have my mobile phone number. They never asked for it. Also, on multiple occasions their online banking was so broken that one wasn't even able to use it. The plus is that indeed, if something goes wrong, after a long time of inconvenient waiting, a human will eventually pick up the phone. The drawback is that sometimes they are so technologically broken that fixing things will take ages.

I recommend distributing even small sums of money across as many accounts as you have. Some in Revolut, some in Wise, some in a normal bank. There is a number of reasons for which access to your bank account can be blocked (fraud attempt, stolen SIM card, stolen card etc.) so the more backup you have, the better off you should be. As the person above said, keeping printed receipts might also be useful for legal purposes.
