POOR, IMPROPER & UNPROFESSIONAL SERVICE

I have had a cellphone contract with MTN for several years. I was contacted by MTN and told that I am due for an upgrade 9 April 2020. I proceeded with the online application which I completed over the phone. I was assisted by a rententions agent Boitumelo Phusoane. I then received two messages from mtn stating that my mtn authentication was successful and another message containing the OTP which I gave to Boitumelo. Three days later DSV Couriers contacted me confirming my address and a delivery date. Boitumelo confirmed that my upgrade was successful. I have sent Boitumelo Phusoane a few emails which has not responded to. When I call contacted mtn the rententions department are sending me pillar to post telling me that mtn recently moved to a new system which only the person who did the applications can log into and view its status. Mtn's turnaround time has been poor and I have received unprofessional service. This entire upgrade application has been unpleasant to say the least. If MTN cannot deliver I'll gladly apply for a cellphone contract elsewhere. There is plenty of competition is the telecoms industry - there's absolutely no need to be loyal to mtn who continues to render unprofessional and improper service to its customers. This new systems that mtn has moved to is clearly hindering their employees from executing their jobs.
