Coolwinks — cashback not received for more than 20 days

Address:

New Delhi, Delhi, 110016

I am supposed to get 1500 cashback for my order on coolwinks and i have been calling the customer service for past 7 days . firstly they don't receive the call, they keep my call on waiting. when they receive they say we have forwarded the issue it will be credited in 2 days and till now i have not received the amount. I REQUEST YOU TO TAKE STRICT ACTION AGAINST THEM AND FINE THEM WITH HEAVY PENALTY FOR CHEATING THE CUSTOMERS. IF THIS ISSUE IS NOT RESOLVED HERE I WILL GO TO THE HIGHER AUTHORITIES
