Vihaan direct selling India Pvt Ltd Qnet India - refund not credited

I have applied for the refund. They accepted and promised to be settled in some days. buts its been *.* months and I'm nor getting proper responses also. I paid ***** to them. I didn't take the product also. But still they are not giving responses. I called to that number also no use. I'm paying interest for that money also. It's making me down mentally. Please do the needful.
