Faulty Samsung Z Fold 3 not fixed after repairs

Between Vodacom and Samsung i have been suffering with a Z FOLD 3 which was supposedly meant to be one of Samsung flagship phones. The phone is barely 8 months old with not even a scratch but gets stuck in countless bootloops, applications crash, it gets so hot that you cannot even touch it. Sometimes it will stay stuck in a bootloopfor upwards of 30 minutes and sometimes even till the battery dies. I have tried running the phone in safe mode and even deleted apps one by one to try and find the fault. I use this phone for business. Its embarrassing to be presenting on a teams call and have a phone fail in the middle of it!

Its in for repairs again after a generic software upgrade was done previously. The technician said that it will now get escalated and they will investigate further.

My issue is that once the "year 1" warranty is over between Samsung and Vodacom they will not replace the phone. I am paying R1899 per month for a phone. I don't think its a lot to ask that the phone work properly.

I have been a loyal Samsung user since the Galaxy S3 but sadly am considering moving over to Apple.

Between Samsung and Vodacom can they please sort this issue out. Either replace the phone with a new one or refund me the device fee for the 8 months I've had it and take your phone back.
