Utterly disgusted!

I purchased a samsung A30s from the Richards bay store late nov 2019. Within 2 months of using the device, i encountered numerous issues. Battery was not holding for more than half a day, phone was over heating and i was unable to receive any calls. Device was booked in, and i certainly expected a replacement / new phone. Same device was repaired and handed to me about 3-4 weeks later after numerous follow ups with the store. I expressed my discomfort and advised the tech rep accordingly. He assured me everything was fine and i wouldnt have any further problems. A month into using the phone, device is unable to charge, still heating up and my incoming calls are still restricted! I called the tech department again at the Richards bay store and he advised me that i would have to bring in the device again, and wait 2-3 months ! Really! I purchased an expensive item from your store, and after all the delays and problems ive already experienced, i have to deal with this? Is this really the service levels you offer to loyal customers? I will personally never ever buy a device from you again!
