Inconvenient - helpful

I recently contacted MTN to upgrade my package from a mychoice 200 to a mychoice 350 as i needed more voice minutes. No device needed, so one would think this would be an easy change over. My started noicing i was not receiving any emails or whatsapps. I contacted the call centre again and was advised I have no data, which I loaded, the consultant then advised me I was put on a package with just minutes and could only get this resolved on Monday between the 8 - 5 hours. Sunday evening my service becomes suspends and I now cant make calls. I call the call centre this morning to check for some assistance and they advise they can help load minutes or do anything to assist, no team leaders available to assist either. They give me the sales department number to contact, only to find it doesnt go through as the service suspended. The consultant on line tells me to find someone elses phone to make the call. I am totally horrified by the incompentence and inability to assist.
