Faulty Device/Inadequate Service

Today has been pretty one one of the baddest and exhausting days with Telkom. Consider I use to work for them.. I never had an issue until today. I bought a Samsung A70 device from them last year December. Ever since last week the phone is always having the message that says USB connector Connected & Disconnected. The phone now does not go to sleep. It's always on. My battery consumption has doubled as the phone also is over heating. I went to the Telkom store in Cresta. The Technician there that was meant to help (Mr Jan Ledwaba), seemed confused did not know what to do. I donno if they get training on such. All he could say was he could book a software issue for repair. I advised him I use to work for telkom, the repair process is you guys will book it, bill me R1500+ if that is still the amount and I will be inconvenienced by not having a phone. again this phone is not even 3months old. The way it turns so hot it, feels like it will be another Samsung devices that blows up in a customers. I stay with the phone I will be asked why did I not report, I do. Then I get a Deere in headlights that has never seen the issue. So it's damned if you and damned if you don't. It pains me because, i spent 2 years at Telkom dealing with such. It just pretty much sucks when the role is reversed. Would have thought this would be better.
