[Resolved]  Oxford Publication — Rejected my project and didn't refund 750rs

I took a job at Oxford publication and they provided Me with a book a lot of 30 pages. I wrote it all day-and-night and submitted it before the timeline And it reached the given address in 3 days And since the day it reached it's been 10 days I still didn't receive any payments so I called the customer care number and He picked up my call but he told me to never call on this number again and hang up without even listening to my issues And when I called another number then they told me to call or WhatsApp on this number so I WhatsApp that number but they told me that they my project is rejected but I told them to at least refund my 750rs security deposit but they didn't even do that .They say that because of so many mistakes they cancelled my project without actual proof, they just sent me my project photos but not the booklet they've give to compare it with.And that's why they cancelled my Registration and cannot give me any refund.
