Address:

803 b wing shiv shrusti, Kandivali west, Mumbai City, Maharashtra, 400067

I bought the shoes for my office wear on 21st of september and in 2weeks they are torn i just used it for office purpose. They are not worth 3000. Plz suggest me procedure to return or exchange they are not worth rs 3000. I have hardly used it u can see in the pucture sole coming out. Tresmode shows we should not believe on this brand. Kindly resolve my issue at the earliest. Should i go yo mall again or it will be resolved here.
