Be alerted for Nedbank crypto investment

I have come across an investment platform on telegram and they said is a Nedbank investment with crypto currency, which is bitcoin to be specific, I invested R10k all in all and their returns were quite good in a short period of time. My investment was handled by someone who was identified as manager by the name of Elizabeth Khaugelo with a telegram profile picture of a white lady and it was also mentioned that the owner of the platform is Mike Brown, because there are lot's of ****mer on telegram, I Google to check if the platform was legit and found that Mike Brown is referred to be Nedbank CEO and I was confident that is a right platform to invest with, until when the time of withdrawal of my profits come, then I was taken from Pilar to post, I was asked to pay more money which they said was penalty fee for incomplete KYC on the back office, I comp**** and now as I was expecting that my withdrawal will be processed, I was further being asked to pay R3500 for wallet activation and I comp****. The next thing as I was now being told that I will receive payment, it didn't come forth. Profits payment that I was to receive was R36k and to this date I have never received anything instate Elizabeth Kgaugelo was claiming that there's something wrong with my crypto wallet and payment was processed and my wallet couldn't receive payment as it needed to be unlocked with R7500. I had to abandon the whole process as it was not making sense, If anyone out there have experienced the same, please help me I would like to be paid was is due to me or else be refunded all my money.
