The worst pathetic service ever

I am Buli, I app**** for a phone online on month end of march 2022, and I told the lady that was assisting me that I want to use my existing number and she said I will do that after I received the phone. Well the phone was delivered and phoned the customer care and I was told to go to the mtn branch.went to the mtn branch at fourways mall and they said I must buy a new sim card Rica it and do porting because this was supposed to be done when I did the application.. fine did all that phoned the customer care activation and I was told to wait for 10 days then everything will be fine, 10 days passed still nothing has been changed. Called customer care again they told me to go to the branch and when I go there they say I must call customer care, so they were just sending me from Piller to post no one wants to assist it went on for two months April and may with no solution I ended up leaving it and cancel their insurance because it was pointless because I was not using the contract sim card.. I left it like that and continue using my prepaid number....Now Friday the 10th of June around 10 in the morning my phone wasn't working no network when you call my number says it's not available on the MTN network called customer care with another phone they told me now the my prepaid number is now on contract haaw really I was surprised because they couldn't do this for past 2 months ok fine I was told it will be active after 24 hours, waited after 24 hours still my number isn't working until now when call customer care no one knows anything they are all useless and *********** I can't receive or make calls and messages their useless agents they just put me on hold or drop my calls when I call ...Mtn is the worst network provider ever I have been with Vodacom I have never experienced this.. and why must I pay for the phone that I can not use this is Bull**** network provider ever
