Freezing my account based on lies fabricated by a shady individual

I've been a capitec customers for many years but 2022 is the year I will be leaving this partnership. I recently found out my account was frozen because a shady man claimed money had been deposited from his business account to my personal account **********ly. Capitec froze my account without getting to the bottom of this issue. There is no ***** case against me, yet Capitec has frozen my account over accusations from someone who isn't even their client. How is my hard earned money frozen due to ***** but there is no charge of ***** leveled against me? Instead, this shady businessman signed an agreement at the police station stating that he owed me money but after paying what he owed me he went to the bank to make bogus allegations against me while I was in hospital giving birth.
