Kenstar — kenstar cooler has several problems but no help from customer care

Website:

www.kenstar.in

Worst service provider ever experienced. I purchased a cooler from kenstar where they provided me a problematic one... I have been following up with kenstar to get the problem solved even these people are not able to make things done.. Then what is reason behind giving all fake promises in manual that there is home services. Suggest not to buy this product because their service is worst. Customer care number never works, no reply of emails.

I need either refund or exchange.
