I invested with someone(moderator) of a group on Telegram called Worklite Uni Options, her name is Lora. I did some research and did not find anything bad. I did contact a lot of the members for reviews or if they had been paid and no bad reviews, everyone got paid per plan, thought surely not everyone lieing (10 people). It was a 21 day payout. My 21 days is up and now all of a sudden she wants a TVN (trade verification number or code) to verify my profits for her server to send my profits.
Telegram is full of scams and scammers, I'm sorry that you became a victim of one of the scams that they run on multiple social media platforms to lure in users and then accumulate all those users on Telegram for all their dirty work. The users that you approached within the community or group to get reviews from are probably a part of the scam which is why you didn't get a bad review because it is all part of a master plan.
Such scams are pretty common, which is the reason why they always target newbies they know if someone is experienced they would know their plot and they won't be able to get any money out of them, and they always take money in multiple steps to make people not get suspicious. If you have already given them money for investment, don't give them more for verification or a TVN number or anything.
