[Resolved]  Elite Services — the website I worked on called salary profile didn't work on the day of submission

I was looking for a job on quikr and then I got a message from this no. In WhatsApp talking about a data entry job which was quite easy and I did all they required... Then when I was submitting it then the website shut down and the person who talked to me also blocked my no. Now they are asking me to pay for breach of contract... Rs.6700 because I didn't submit...the only thing here is that the company has no website or official info and the website I worked on called salary profile didn't work on the day of submission
