[Resolved]  Link Star — threatening me to pay for not completing my work

I am nazia noor. On 6th april 2019 i got a email about a company named as link star. They told me to there is an online work of form filling which they will pay about 30000 rs. They will provide me 3000 forms which i have to complete within 15 days. Now they asked me my email address and send me an mail without complete details of agreement. They also asked my mobile number and send an otp telling that it is for mobile verification. And i don't know how they digitally signed the agreement and send me a mail containing the login id and pasawork and one customer care number and a link of the company. When i click that link and login into it with the given id and password. But i was not able to understand what i have to do so i called in the customer care which was given to me but it was not working. After that i forget to that work. After 15 they started to threten me that i have to pay the penalty for not completing the work. They satrted calling me and telling that they are from legal department and alsi send me a notice on my mail redarding the penalty. At that time i got scared and i paid whatever they have asked me to pay. I have paid around 16890. They also provide me the noc for the payment. After 3-4 again they called me to pay 12000 rs. Please resolve my matter. The two number from where i recieve the call are [protected] and [protected] and i also have also the notice amd noc pdf.
