MTN do not respect their customers they only care about money

I Made an upgrade on the 4th of April till today my handset is not delivered I call MY every second day but I never get assistance; I have spoken to More than 10 Agents ; a supervisor called Nadia and 3 complaints department Agents but no help.i have been a loyal customer of MTN MEN for years and they are now treating me like trash while I pay money for their services ; they do not have s****s to solve problems ; how many calls; Agents ; Superviours will it take for one problem to be resolved; How long does it take for one to get assisted by MTN; I want a refund for the payment I Made I can't keep paying for pour service I'll take my loyalty to another network ; I'm tired of talking to MTN employes who clearly do not know their work , to make matter worse the Agent I spoke to today hanged my call after 25minutes without saying anything ; how rude and unprofessional is that...
