appalling serviced received from mtn

I bought a Huawei p10 lite last year October for my wife and there's always system updates popping up on the device so we always update it to keep the phone up to date.On Wednesday the 13 June I put the update to download and after downloading it asked to reboot the phone to install the update thereafter it never came on and had an error message stating the device has failed verification and may not work properly we followed the prompts and it refused to connect to wi-fi to download erecovery.I then visited the Phoenix mtn branch the next day(Thursday the 14th)and spoke to a guy named Azgar who told me that I shouldn't have downloaded the update which I couldn't understand coz how else would I keep the phone up to date he then told me to go to We fix in gateway and they will install the software free of charge so we went and they told me that they cannot help me because they don't do devices that is still on warranty they only do out of warranty so that was a waste of my time!I then decided to visit another mtn branch on the first level in gateway I then spoke to a guy named Deraj explained my story yet again he first asked me which branch I got the phone when I told him he seemed not interested to help coz I didn't get the phone from that branch which is very frustrating because it shouldn't matter where I got the phone from it was from the same company he then told me I need proper WiFi and not from another device coz it won't work I should go somewhere with free wi-fi and refused to even connect to the stores WiFi which I'm sure they had; he also told me that he could send the phone to the repair centre but it's going to take 30 days at that point I was enraged because she couldn't be without a phone for a whole month with no spare phone to use I was furious because everyone seems to have no customer ethics whatsoever!no one seems to want to assist me with a device that's still on contract that refuses to come on.i then went to MTN's direct store(1383)and spoke to a Huawei promoter/Consultant named Craydon who tried his best to assist me even connected the device to the store WiFi and yet it refused to work; unlike all the mtn employees he continued to assist; he spoke to another guy from his region on a call and explained the problem they couldn't seem to fix the problem there so he took my phone in to try and help solve the problem he said the most I would wait is 1 week it's still inconvenient that my wife is going to be without a phone for 1 week but we appreciate the help that someone is trying their best to help.I am deeply disappointed with the service or should I say lack thereof received from the previous 2 stores they showed no interest at all in assisting and it's sad to see that a Huawei consultant showed more compassion that the people that were suppose to help!
