Philips India — faulty trimmer not being exchanged or returned

I purchased philips mg7715/15 multigroom 13 in 1 trimmer on 17.01.2018 from three way electronics at haji ali, mumbai. The product specifications mention a smooth shave while it leaves a stubble on shaving body parts. The seller refused to take it back and directed us to contact philips service centre at byculla. Service centre refused to help in this regard.
Then i contacted customer care and they opened a work order number wo160-[protected] on 23rd march. Customer care again referred us to byculla service centre and closed the work order without any further action.
I contacted again and got work order on 28th march wo160-[protected] which was again closed without any action.
Kindly help me return this product as customer care and service centre both are not responding.
