Pyramid Scheme Scam

I invested $25000 and the gave me an extra $10,000 as a joining gift, I did quite well at first, but when I requested a withdrawal, they said I had to open another account and deposit $10k in the account and they would put my money into my account and give me my money plus my $25k back within 15 mins, I never as appeared to be a scam and they should not be trusted, the whats app, communication I had with them was deleted, initially I only lost $25000 of my own money,i was able to withdraw with the action of AssetsClaimBack advisory still my advice is not to trust anyone who deals with this type of scam.Wish I had done my proper research before I even considered trying them out
