Horrific service by both CUSTOMER SERVICE AND TECHNICAL

I am absolutely fed up. I have an MTN sim card in my wifi ****le, i called MTN on the 26th March to help me with my internet access for online gaming, they said they need to grant VPN/APN access on my sim and it will take 2-24 hours( ref number: 1- ********** 7166). Cool. I called back after 24 hours to check the status, they said no its 2-48 hours. Ok fine i will wait one more day. After 48 hours i called again, now the lady says to it takes 2- 48 WORKING hours. So i tell her what the previous 2 people have told me and she apologises and says she'll escalate it(ref number-1- ********** 306). Now it's the 4th day in a row that i have called, the customer service says i must call the technical department because they load the VPN onto the card, so i call technical, they said i must call customer service because they load it onto the card and then you must call us back to configure your wifi modem. So now like a ****** i'm calling 2 departments back and fourth. So i asked to speak to a supervisor, the lady said the supervisor is on lunch and will call back after. Guess what, it's the 11th April and nobody has called me back or has loaded the VPN or APN or whatever the hell needs to be done on my sim card.

BTW i called vodacom to do this on my cell SIM and it took them 10 MINS!!!!

IT IS 16 DAYS LATER AND STILL NOTHING FROM MTN!!!

I need a resolution on this TODAY! Kindly get someone in seniority to call me and resolve this TODAY!
