[Resolved]  Fini Technologies — I'm complaining about this technology because they are harassing to pay the money

Hi,
I have joined to worked for fini technologies. I have payed the initial money for joining and after that i wasn't able to submit the work on the given time so i extended it by paying 7k again. And submitted the work on the given time. But now fini technologies people are calling and asking to pay for the money and they are threating saying the a case has been filed on my name. This is very fraud. They are trying to get money from me.

Please help me to get out of it.
