Telegram complaint: Online fraud

I have been contacted by somebody thru whatspp for online job and later on directed to telegram user id @Laila_working9067 and @Gaurav_working456.
I have been told there will be a tasks for every 3tasks will be paid and after few tasks i have been told i have to invest for prepaid tasks in return will get the same with commision .i have invested 2k and i got 2.8k .
I have asked to invest 5k and later 30k once i invested both 5 and 30k i have been told due to some changes in online order i need to now pay 1lakh 20thousand to complete tasks in return will get completed amount of invested and commision.
I have realised it is a scam and they were trying to convince me to make 1,20,000.
I have blocked them and reported.
I don’t understand how come telegram or whatspp doesn’t take any action on these people and how come they allow to creat account.

I hope telegram will definitely look into this and put a full stop and not allow the scammers create fake accounts
