Tired of this Cat & Mouse

I have funds I've been waiting on to be repatriated from Capitec bank & still haven't reflected after being promised on the 13th of March they would be in my account within 3 working days. Monday the 18th of March i was told a request of the funds was only processed on the 15th of March so monday the 18th of March would count as the 1st working day & the matter has been escalated, so the funds should clear by Wednesday the 20th of March 2024 & today once again the 25th of March i called & tried to follow up as to what is going & the agent asked me to hold on but after a while she just hung up. I therefore resorted to send an email address that a complaints department agent sent me an email on last week monday the 18th but it turned out that email address doesn't accept emails. At this point, what must one do with such poor customer service? All i want is my money then leave this bank for good.
