John Players — cotton trouser

I have been a coustomer of john player for last 15 years. About 8 to 12 months before i bought a cotton trouser from kotri shop kota (Rajasthan). It got wrinkles in such a short period. Today i visited this shop. He said that john players provides gauarntee of 2 months only. After 2 months no gauarntee. I have never experienced this type of problem before, today also i have
Purchased 2 trouser worth rs 3800.00. Sir keeping record of purchasing is not possible but the tag john player is sufficient. I request that the defective trouser should be change without any question like bill or period.
Thanks
