Cheated by MTN

I upgraded my sim contract on 22 July 2020 and never received what I was promised. I contacted the call center and the consultant was only too happy to earn the commission on the sale, but since then I have called MTN client services everyday and been receiving the run around. I was promised 200 anytime minutes, 15GB day and 15GB night data and 50 sms's for R199.....I got 50 anytime minutes, 15GB data day and night and 50 sms's (my previous package was 150 anytime minutes and 1GB data which I was fine with until the consultant offered this to me)......I am now currently incurring huge out of bundle charges on my calls... I have been a loyal customer of MTN for the past 21 years and if this is how they treat loyalty then I should move to another service provider. I am shocked and disgusted by the service I have received and have been on the phone since the 27th July 2020 till date trying to get someone to help me... I speak to different consultants who promise to help and then my ticket gets closed the very minute I am on the phone.....
