Incomopentance at MTN

I have now been trying to do an upgrade on my Data line since Feb this year. First your online company Mondo left the transaction is approved state for a month and nobody could advise when the device is being delivered. Cancelled the upgrade and got your agent to phone me. Adelaide Kgaphola was helpful at first but again 3 weeks later she does not repsond to emails and nor does she assist in getting the query sorted. Complained on Twitter and guess what still being escalated since Saturday. This time around it is an issue between MTN and DSV where DSV does not want to phone me on my cell but rather my data line. Go figure that one out. Everybody blames everybody and nothing is being done. So please now you will cancel my upgrade and load a termination for useless service received from MTN.
