Meesho App - Received wrong product asked for exchange but no one has come to pickup

I ordered a product on *th march **** and received a wrong product on **th march. The delivery person asked me to initiate exchange in Meesho app. I initiated exchange and no one has come to pickup the product. Called customer support in Meesho they say we will receive the product as soon as possible but it has been a month since I ordered and paid money.
