Xiaomi India — refund enquiry waiting for 2 weeks and no complete solution provided

I placed an order (Order id [protected]) for fast charging cord and adaptor through mi store app on 24th of august. I had to make the payment thrice for the order to be placed as 2 pyments made through tez (At 22:08 from [protected]@okicici to mi. [protected]@axisbank with google transaction id : cicagkd87rmzng and upi transaction id :[protected] and at 22:09 from [protected]@okicici to mi. [protected]@axisbank with google transaction id : cicagkd87tm9ea and upi transaction id :[protected] did not get detected by mi store app and with the 3rd pyment which i made through paytm was detected and order got placed. After sending all these details to mi customer service through email, i got only 1 refund for 1 of the 2 tez payments on 28th august. No delivery of the product way after delivery date and order state in app stuck at shipped. Send another email stating only one refund has been given and no product delivery, but as response was not helpful, chatted with an advisor who informed that delivery will not be done as delivery address is in kerala. But reassured that both payments left to be refunded will be given back in 8 days. Got 1 refund to paytm when they cancelled the order, but still no third refund. Emailed again stating the same and asking for rrn so i can check with bank if they have already processed it. But the response was blunt stating tat they have received ony 2 payments altogether from me and so nly tat has been refunded. I cant understand why will it show only 1 payment from tez when both were made the exact same way within 2 minutes gap. Clearly other payment that have been refunded is the 3rd payment as it came back to paytm wallet. Chatted with arpitha and shashank shanker today wherein bth put me on hold and never came back even after waiting with no response for more than 15 minutes with each prson. I wnt my money bck with proper compenstion for the time wasted waitin for the delivery nd refunds nd inconvenience.
