Nafa.in — not doing payment and telling lies

I had sold my gift card worth of around RS 5100 and gave a withdrawal request on 6.12.2018. no response to my mail and yesterday message came from official what's app no. Saying your amount is processed and will get credited in 3-4 hours, later I realised that was a lie. They are holding my money and not giving not communicating.

I have send many mails and message and asking to give my money. There is no replying. Nafa is an unethical company or individual. They have committed to do the payment within 3 days and it's been around 7 days.
