Poor Workmanship

Got a P40 lite and the phone is only 7 months old I never used it but it gave endless issues and the battery doesn't even last a day. Took the phone in for repairs. When I got it back my screengaurd was ********** and replaced with a plastic. Secondly the phone now looks like an old phone that has been repaired on the streets because on the sides where the silver part is it's scratched so one can clearly see that's where they opened the phone. I used the phone for about a week to see if the issues where resolved only to find out it's still the same. I then returned the phone and stated that I don't want the device any longer as the problems still exist and what's worse is the fact that it now looks like it came from a backdoor technician with all the scratches on it. Got a call yesterday stating the phone is ready for collection. What ****es me off is the fact that they don't even have the decentcy to return the phone at the branch where it was handed in and completely disregard the fact that I said I want a replacement phone as I'm not hoing to pay 3 years for a phone that has been giving problems since day 1 and that it came back looking like a old second or third hand phone. Does Vodacom technicians not take pride in their workmanship. I DON'T WANT THAT PHONE LIKE I STATED ON THE REPAIR SLIP. So why was I called to come and collect it.
