Coin exchange India pvt ltd - No refund given to my account

I received an invitation through wp. And after clicking on it they asked me to install telegram. I was added to a group named as task group where more than **** members included. I was unable to message on.the group as it was restricted and only allowed admins to post anything.
They gave me tasks to complete which was a few links which directly takes you to google to give reviews to some restaurants and hotel. For every * tasks get completed,they were transfering rs *** or *** to my upi account. On *th task i was charged to deposit rs **** and i did so. They refund me ****. After then on **th task they charged again **** + **** for top up. Again i deposited and within * mins i got back rs **** to my account.But when i reached the task ** they charged rs **** to get deposited.
And sent me an agreement copy through the chat, to accept it. I deposied the amount of *k. Now they asked me to do a top up of rs ***** to get back the total amount. I argued to them but they forced me to complete the order of **k. And i don't hv any other option to get the *k refunded. So i tryst them and deposited ***** again. They made me wait fot ** mins and asked to complete the *nd order which was to deposit **k more, so that I'll get all the money refunded. I got a goosebump and stopped it immediately. I requested them to refund my money but they didn't

I went to the scoin investment website. And clicked to the withdrawal option,added my account details. But it is showing error.

Plz help me to get my money back
