Trash service, trash repairs, damaged phone.

I took my Samsung Note 20 Ultra there for a battery replacement. They charged me R900. Got the phone back quickly and was initially impressed. Only to get home and the phone stopped charging or coming on during the night. I brought the phone back, they then told me that the motherboard had a fault, note that the phone worked flawlessly until I brought it to them for repair. I tried calling in to find out if there had been any progress on the phone, only to find that they were call forwarding my number to avoid me. I am now standing in their shop to get my phone and it has been 30min now while they scurry to find my property that they damaged. I observed the guy sitting at the desk take the plugged in ribbon cables and put them on his tongue to check for voltage. They used an old tooth brush with what appeared to be meth spirits to clean terminals. These guys are red lights across the dash. Take your phones elsewhere.
