Capitec bank is not to be trusted!

Hello, i am beyond disappointed with Capitec bank again. A few weeks ago i wanted to purchase car parts from my usual supplier who is using FNB. I later received a better deal from another supplier who is a Capitec holder. I then transferred R28 000 from my FNB to my daughters Capitec account. I paid for the parts. Later on Capitec decided to put the account on hold without notifying me of the reason why. I could not access my banking app. I went to the bank to inquire and i was told it's because they suspect a ********** transaction. They then told me to present an affidavit, proof of payment of where the money is coming from and id copy. I submitted all the documents but still my account is blocked. What ****es me off is that they blocked the account of the supplier and also he sent money to another lady, they also blocked that lady's FNB account. It's now a chain of blocked accounts. Yesterday i returned to the bank again to ask them for any progress. They also have no answers and they keep on transferring my case to different departments and i end up not getting any help. I don't mind moving my daughters account to another bank but why are they involving other people and they get their account blocked too?
