Clarks — Clarks/Privo shoes damaged

I've bought a Privo shoe from the INC5, Esplanade store in Kolkata, and the sole is completely damaged after limited use. It's a shame that such an expensive shoe got completely damaged so easily with only a 60--70 days office use (no harsh usage involved) .

I bought it on 21st August, 2022 and started using only from end of September.
Place of purchase: INC.5, 15/2, Grand Hotel Arcade, Jawaharlal Nehru Rd, New Market Area, Dharmatala, Taltala, Kolkata, West Bengal 700013
Price: INR 4K
