Skechers India — sandals bought from south extension showroom

Dear sir/madam,
I am a very loyal and extremely happy customer of sketcher products. Have bought so many products both in india and usa.
I had purchased sandles 2 pairs from south extension showroom in new delhi in may or june, don't remember the exact details. You can get the details by linking my phone [protected] and name vineet bhatia.
One pair was defective and the strap came off in 2 weeks. I put my complaint to south extension showroom sales staff. They took pictures of the product and assured me that they will exchange it once they get approval from company. Till date they are only delaying and not giving any positive feedback.
Please help
I have given my phone no. For records

Thanks and regrds
