Lotto Sport — sole crack

I'm sorry to inform you that my very first experience with Lotto product is not satisfactory. As I had purchased a pair of sandal @₹1499/- in April and now I noticed that it's sole is cracking. It's just about 4 months of purchase & it is used for office purpose only.
Now what I may expect from the company. May I get a replacement for it, if possible.
Please consider the matter and do the needful as soon as possible.
I have sent an email to [protected]@sportslifestyle.in regarding the same but didn't got any reply yet.
