Flipkart — No refund but product has been picked up

I placed a return request for a defective phone nothing phone 1. For which technician visit was scheduled. Technician came and confirmed his identity. He said that the product needs to be pickedup as it cannot be repaired here and your return is approved. you will get refund and the status of the same will be updated soon on the Flipkart app however no status got updated. And my return was also rejected
at this point of time, i don't have any product nor i have any confirmation about replacement or refund. the seller was Indiflashmart and the technician was sent by jeeves via Flipkart. I want my money back
