Flash ****med me

I am so disappointed with Flash Group. I have made a deposit of R18600 to my Flash account, they then blocked my account saying I must verify myself. They asked for a whole lot of documents (ID, selfie holding ID, proof of address, proof of payment). I sent all documents and they have confirmed all documents are in order and my account will be open again within 24 hours. After the 24 hours my account was still blocked and I called them again. They asked for same documents, I sent the documents again. I don't even know if they don't have a system that stores these documents they keep asking for. I was then asked to make a login attempt in 24 hours and my account would be open. After the second 24 hours my account was still blocked and I called for the third time, I was requested to send my selfie holding my ID as the one I previously sent was not clear. I did take a new selfie and sent it through, I was told again my account would be open in 24 hours. After the fourth 24 hours I called again and I was requested to send the proof of payment as they can't find it on their system. I did sent it though again and I was told I'd have access to my account within 24 hours. That's the fifth 24 hours they are telling me about. Ok, I waited 24 hours and still no access. I called again and I was requested to send though a proof of payment, which I have already sent twice. That's when I noticed something is fishy, I was all confused and asked why they keep asking for same documents everyday and telling me the account would be open in 24 hours. They rep**** by telling me the proof of payment was rejected, I asked for what reasons is the proof of payment rejected. They said it's rejected due to its font. I asked them why can't they verify it with the bank instead of just looking at it and reject it. Since the payment was made from an fnb account why can't they verify the proof of payment with fnb? Then they hang up on me. I am being ****med thousands of Rands by Flash Group and I'm not happy at all. I just need access to my account then I will use all funds in it and leave them in peace.😭😭😭😭😭😭
