Inferior product

I didn't know that an upgrade can be the start of a nightmare. I did one recently & it has been the worst experience ever. On Saturday, 14/09/2019, I did an upgrade at a Telkom store at the Eastrand Mall. The very same day, I noticed that the device is auto-typing. In frustration, I packed it away. On Monday, 16/09/2019, I contacted Platinum Warranty & they indicated that a technician will contact within 24 to 48 hours. The technician called me & we arranged that on Wednesday, 18/09/2019, he will come through to access the device. He came, accessed & took the device with him. On Friday, 20/09/2019, in the morning, he called to say the device is ready & he will come to drop it off. He came, dropped off the device. We punched few buttons & the device seem to be working. In exciting, I packed it away & looked forward to coming back home after spending time with the family to start working since I had work as I gave away my old laptop after getting this one. To my horror, the same issue (AUTO-TYPING) had somehow reoccur. You can just imagine my frustration. It seem like the device never went in for repairs. As I read other reviews, I'm convinced that these Mecer products are not really repaired, they are just recycled. They take mine & give it to somebody while they take somebody & give it to me!!!
