Account unfairly blocked without my knowledge

I’m a reseller of preowned items, I’m an entrepreneur, I meet a variety of clients on a daily basis while selling online. Client happened to report me at capitec while having my item with her, I told her to return the item so she could at least get an exchange if not a refund but she blocked me and reported my account, it’s been two months now going to three trying to communicate with capitec and there’s no response. Capitec closed my account without hearing the side of my story because client has my item with her. My business is stuck, I have responsibilities I have to take care of as the breadwinner at home. Please kindly assist with this matter I am facing. I’ve been using capitec for over 5 years and I am so disappointed with my experience with capitec
