Crocs India — crocs literide slippers men - very bad fit

Address:

Gurgaon, Haryana, 122002

I had purchased crocs lite ride slippers sko-lo rajiv nagar sec 14, gurgaon vide bill no 1011 dated 11/10/2018 for rs.3495 the right side of the slipper has manufacturing defect as it is hurting the inner side of the thumb and the first finger and the back side of the toe automatically goes out of the slipper. I had been wearing crocs slippers for last so many years but for first time i had this kind of experience. This is really a major problem which i think would be in all the slippers of this model. Crocs are known for their comfort but i am really sad to say that your quality has gone very bad and no quality control checking has been done on this model. I need to give them back and want my money back. How to go about this
