Maxbhi.com — Iphone 8+ screen

Website:

maxbhi.com

I purchased apple iphone screen from maxbhi.com on 7th october 2022
Order #5109240,

i received the product in 5 days but the product was faulty ( screen was not working)
i raised complaint with maxbhi.com they ask to send the product back (on own expenses) and they will replace.
i send back then after 10-15 days they accepted there fault and send another screen; same issue was there with this screen as well.
again i send back the product and as off the day they are investigating; i requested for refund as now i don't have hope and faith that i will get a good quality product but maxbhi.com team is denying.

kindly help
thanks
