TYME BANK RANDOMLY BLOCKS PEOPLE'S ACCESS TO THEIR BANK ACCOUNTS!!!

I left work today, 01/10/2024 and stopped off at a shopping centre to purchase some groceries. I used my Tyme Bank card for this. On getting home, I opened my laptop to log into my Tyme Bank account, only to get a message that my account was blocked. This was done on both my internet banking as well as on the Tyme Bank app.

On calling the call centre, I was transferred to the ***** division, but while holding on for my call to be transferred, I was cut off. I then called again and asked to speak with someone in the ***** division. When eventually getting through to the ***** division, I was told by the call centre agent that access to my account was blocked, but they don't know why.

What sort of bank is this that just randomly blocks access to your bank account without knowing why your access was blocked, and without first checking with their customers if certain transactions were actually done or not?
