Worst Customer Service MTN

Recently upgraded my cellphone contract - Only the package, no instrument upgrade. Received an SMS notification that the plan was loaded 13/11/2020. Upon enquiring as to when the once off promotional data was to be loaded I was informed within 3 days, I even got a call reference on 13/11/2020 after 2 calls. I followed up again up and was told it was 7 days, then 24 hours then again 7 days. I made in excess of 18 calls and was told it was escalated and gain it would be between 2-24 hours. I turned to Social media and the Facebook comment advised that my call reference was being investigated, The Messenger app advised me that my contract was terminated 13/11/2020 - I currently have 3 contract all active with MTN. This is the worst service delivery i have had from MTN in my 20 years of being a MTN subscriber.
