Their executive make fake account and comments on your reviews that this is a fake review and they have got 12k cashback. Mr Qaisar khan is an executive in cash karo who is doing all the mischief.
Check all the below reviews and even check their fake positive reviews which they are posting just to increase their stars here.
Mouthshut have enabled a fake tag in it and I guess after 2-3 days they will say Mouthshut is a fraud and liar who are paid to malign their reputation, LOL.
