Limeroad — return request

Address: Chromepet, Chennai, Chennai, Tamil Nadu, 600044

I ordered a product and the size was not a good fit. So i placed a return n replace request. But the return pick up of the product is getting delayed for abt a week and i confirmed to pick up on sunday (3rd nov) since i will be available. But the pick up person didn't turn up n called me monday morn and enquired abt address. I told i will be available till 10 am morn and after 2 pm noon the same day. He refused to come in that time slot and postponed the pick up. Now i received a message that i refused to hand over the return product so return is failed. I wonder what is happening. Please process the return pick up when the customer is available and the service person expects customer to be at home when ever he comes.
