[Resolved]  Pro Techno — blackmailing and harassment during phone call and sms

Respected sir/ma'm,
My name is ayub ali. I am complaining about this fraud pro techno company.
This pro techno company gave me the work which i was not able to complete because of some personal issues. Later on they called but i was not able to pick the call. So they drop the mail that they will take a legal action. I replied them the same day but after 1 day they reverted me to pay just double. I negotiated alot and they asked me to pay 25, 000 which i paid. And they gave me the noc for the same. After 2 days they sent me a message that i have to come to the court and do signatures. I told them it's not possible for me to come so they asked to do digital signs in which i have to pay more amount.
I am really very tensed. Please help me. N tell whether the company is fake or not?
They are continuousely calling me and blackmailling me, pls help me.
