Account frozen with no warning

Capitec decided to freeze my account due to a payment I received from someone else (Calling it a *****ulent payment). I have spent over 40 minutes on the phone with them They made me get an affidavit to explain that I get payments from an online crypto trading platform. After doing all of this, I have to run around and do everything for them to try and prove that I did not receive a *****ulent payment. Your service is disgusting Capitec. I had to borrow petrol money from someone because you decided to get clever and froze my account. No notifications or communication from your side. This is after banking with you for 11 years. Your customer service to loyal clients is SHOCKING!!!!!
