Don't play Betjets

I won a lot of money. When I wanted to withdraw they said I must deposit more than R350. I did that. Than they said I must deposit another R1000. I did that. Then I still couldn't withdraw the money. I asked for help and was sent to a Facebook messenger link. The person was rude and said I must deposit another R2400 before they can assist me. I asked for a number that I can call for assistance and I was told that they don't have telephone numbers. I asked for an email address and they said they don't have. I got angry and said they are ****ming me. (Not in such nice words). I was told that they will open a SAPS case against me if I put n review on hello Peter or if I put a review on Facebook Twitter and Instagram and that I will have a ******** record. I have screenshots of the conversation
