Unconvertible airtime

I have been calling MTN since yesterday morning because I bought airtym of which when I try to convert it to data it tells me I have insufficient airtym. I spoke to almost 10 consultant and two managers. Nico is one of the managers o spoke to instead none of them has resolved my matter. They keep sending me ticket numbers but and telling me about 72 hrs turn around for the matter to be resolved because this is the 1st time to see this kind of problem since they worked at MTN. How is that my problem? I spent the whole of yesterday without doing my business on the phone since they said my data should not be on now today m told ofanother 72 hrs. Hell no. I am running a damn business here.iv never experienced such ridiculous service with my vodacom number. Resolve my matter so I can buy data and use it then leave his ridiculous network. You are busy running your business and I must not and wait for 72 hrs of which no-one is even calling me to give update about the matter. Nonsense!!!!!
