I need my money please

Hello! It really looks like Capitec doesn't care about it's clients. I have been struggling to get my funds available since they have been placed on hold in February. I don't know what else to do because I have submitted everything that I can get and proof that what they are asking from me might not be possible. Here is my story: November last year I saw a post of someone selling a phone on the market place, I enquired about the phone and asked the guy to send me proof of purchase to rule out the fact that the phone was not ******, and he sent it. The phone was still under warranty and it looks good and well taken care of too. Go be safe I also asked the guy what if he sells me the phone and later report it as lost/****** and he suggested that we can meet at the police station for a sale and do an affidavit that state that he is selling the phone to me for R12600. So all was good and we got to the police station, they told us that they are not allowed to be involved in those type of things but we agreed to make our own agreement on that affidavit paper. We made our agreement and we both put our ID numbers (we both had our ID's) and signed. Later that day when I was going through the phone I noticed some odd things and send the guy a message to get clarity but my message didn't go through and I just thought maybe he will get back to me later but he didn't. I tried to be patient and wait for his reply but after 2 days I went to the police station to report because it was clear the guy has blocked me. The police told me that they can't help me and I will now have to go through Small claims. I went to small claims court and got a demand letter that I must give to the guy. On my way there I passed by Capitec Bank which is the bank I used to send money to his Capitec account, I told them the story and also gave them copies of everything I had so far. I went to the nearest police station where he stays and aske the police to escort me to deliver the demand letter because I am a lady and I don't know what that guy will do to me if I try to deliver that alone. We didn't find him since he stays in a security complex, the police asked me to leave one copy with them and they will deliver it the following day early in the morning.

The following day the guy send me a message on that same number asking what the problem was and I told him to read the demand letter. We agreed to meet at the police station again and he took his phone and tested it. He said he wil try and pay me my money before the 14 days of the demand letter expires, and asked if he can pay in bits and I said yes. The following day he first send me R5000 in the morning and send me R7600 in the evening.

In February I noticed that one of my savings account was missing and when I called the bank they said it was frozen due to ******* activity and I was advised to go to the bank for more information. When I got to the bank the guy told me the date and I quickly confirmed on our chats and I saw that R7600 they guy paid me was the *****ulent activity they were referring to. So since then my account was unfrozen but the R7600 was missing. I have been in and out of Capitec bank and I was told to submit a certificate copy of my id and proof of payment. I told them I don't know how I am gonna get the proof of payment because the guy blocked me and I have been to the police station and they told me they can't help me because the guy paid me the money and there is no case on their side. I am so frastrated that sometimes I feel like going to where the guy stays but like I mentioned it's a security complex and also I don't know what he will do to me, I don't think it's safe to go alone where he stays. Please advise me on what to do.
