Capitec terrible customer services!!!

Capitec bank is impossible their service is very poor after they have closed my account due to the fact that I invested in a bitcoin investment scheme of which I wasn't aware it was a scheme as they had offices and a website I went ahead invested then got paid my interest together with my initial investment when that scheme ran away with monies people reported the schemes account then capitec decided to block all those who recieved their interest from that scheme which is so unfair when we ask them to open our accounts they go ahead and require us proof that we can't get capitec is such a terrible service bank OK pass that incident I go to their branch and ask for a confirmation letter that my account is no longer active with capitec Bank they tell me to wait for 3 to 7 days my letter will be emailed to me up until this day its nearly two to three weeks I have not recieved my confirmation letter I also go there for another request of a power of attorney letter to my surprise capitec bank cannot provide that to its clients what exactly does capitec have either than closing down victims accounts instead of dealing with the main account that stole money from people who were trying to invest and earn to make a living they should really open our accounts and deal with that main account that collected lumpsum of money from innocent people and ran away.
