Attitudist — Exchange not done

I ordered my Formal Leather shoes size # 8 in September 2022.
Order number was 237915.
I received my order on the 16th October after paid Rs. 740 in cash but the Shoe size was loose. so I put my Exchange request the same day on their website for size 7.
but still today nobody has come to get the parcel to exchange.
I cannot call anybody in Attitudist because nobody is picking my phone.
it is a very very poor service they provided.
there is no customer care after delivered the product.

I need my money back.
