Foschini Canal walk cellphone department is bad in assisting with a problem

I will never buy a phone from foschini canal walk again,their service is really bad. I bought a Samsung A52s in October 2021 I didn't even use the phone for a full month then it started heating up like in really heating up I took the phone back to report the issue because I also took out Insurance on the device, I was advised by Paul to take the phone to we fix (I didn't even know about the place) on 30/10/21 booked it in for repairs with we fix after many emails and phone calls 2months later my phone was still not fixed. On 02/01/22 I booked the phone out by we fix because of the long wait and I took it back to foschini. Paul then told me that he will book it in and with finrite for assessment I went to the store twice to hear of progress Paul made me believe he's waiting on finrite I only found out afterwards by one of the call centre agents on a telephone conversation that the device was never booked in only after that the phone was collected for repairs. Today 5months a later I'm still waiting on my phone I received a sms on 4/03/22 that the device has been repaired but up until today I didn't receive a phone call from foschini canal walk to collect my device. My question is why am I paying for a phone that I don't have a use of? Why did it take them 5months to assist me with my problem after I didn't even use the phone for a full month. Foschini or Samsung or whoever can keep the phone because I don't wat it anymore and they must give my installments back or credit it on my account I have had enough.
