Dissapointed

Good day. From the start. I have recieved a lumpsum of money from a life insurance after my wife passed away. The money was depsoited into my account yesterday 21/01/2025. Today at 22/01/2025 i recieved an sms after using my card at a shop and declining that they have frozen my money.cleared out my account due to a verification from where the money comes from. Im sorry i dont feel that i have to explain to my bank where i get my money.im pretty sure they do not ask questions where ********s get there money from. What makes matters worse is now i have to wait for my own money 24/48 hours. Im sorry this is absolutely unacceptable. after i visited the branch they tell me they send an sms.with proof i can show when i swiped my card at 09:43 today i recieved an sms.but then it was already to late.no they just pull up there shoulders and tell me i have to wait.this is bul****.i never had these types of problems at my previous bank.
