Mtn putrid service when it comes to upgrades

I am due for an upgrade, a week ago on a sunday, no stock of the s24 ultra and s9 tab. I got a call on thursday that they received stock by the tygervalley branch i went the friday, waited half an hour for service, when i was eventually served, i was told to come back in a half an hour, they still busy unboxing the tabs, i came back i waited another half an hour to be served, when i was eventually served, the uprade process took place, busy over an hour, i was simply told the status is pending, and they dont know the reason they going to do manual vetting, they will get back to me the next morning, the next morning came they never got back to me, i had to phone them, when i phoned i was told they busy with a customer they will get back to me within 5 minutes, as you can see the trend of my story and MTN's poor service they did not get back to me in 5 minutes instead 45 minutes, received a whatsapp from the agent they need a copy of my ID sent it instantly asked how long will the process take no response for 2 hours i phoned back said i will receive feedback the next morning, you know by now i did not and decided to post a review on hello peter for further assistance Ive been a customer of mtn for years had a contract which i paid faithfully for 3 years to be treated by such a poor expercience for a so called leading cellular network service provider
