Williamstag — payment not received

They have given about 160 pages as a project that is to be completed within nov 1. We have submitted the project on date. They said there will be a quality checking for 3 days and after that the amount will be fixed w. R. T the quality we achieved. After fixing the amount, they said to pay rs.3850 as gst. We all had a double mind to pay, but some people posted as this is a reputed company, i am working in it and i have no issues like. So we also proceeded with their words. And at last all their mobile numbers, websites and email id's were not reachable. All were vanished. Please help us. Nearly 100's of people lost money in this. Do consider this as serious issue.
