Myntra.com — refund fraud and pathetic customer service

I had ordered a top for my mom, I received my order on 8th January 2020, however, since the size didn’t fit my mom I had to return it because there was no bigger size available.
On 9th January 2020, your agent picked up the item. But today in the evening I received a message from you guys that my refund is put on hold. I called up customer care and he said that the product was damaged. HOW THE HELL CAN THE PRODUCT BE DAMAGED?? I HAD IMMEDIATELY PUT IT BACK IN THE SAME BAG AFTER TRYING. I guess your pick up agent must have damaged it and now just because you don’t want to give my money back you are putting the blame on your customer.
Your customer care executive was not even able to track my order and when I asked your him to raise a complaint, he said that he can’t do that and I’ll have to wait for 5 working days in order to receive an update from the pickup agent.
I’m your old and regular customer, if I don’t receive my money back, I’ll have to file a complaint to consumer court.
