Skechers Retail India Private Ltd. — service complaint

Address:

Mumbai City, Maharashtra, 400049

My husband bought a skechers shoes from bandra linking road store mumbai (India), he confirmed about the exchange if the size didn't fit. As the size didn't fit me i have visited store 3 times and called multiple times they are not giving me size change. My shoes are lying in bandra store untouched but not changed. Manger of the store mahesh and sachin is such a irresponsible guy not bothered of customer, keeps committing for exchange of size, but never called to keep me updated. Now they don't even attend my call.
Its been a month my shoes are lying with them.
I have knee issue, that is the reason my husband bought the shoes, and as they didn't fit me, next day i went for exchange.
After visiting 3 times they said they will deliver at my place.
Calling them everyday, no response.
Is this the way you guys provide customer service, by harassing us.
Please take stern actions against the store manger and teach him some customer service.
