Exceptionally poor service from MTN!!

My phone was handed in to MTN insurance, and after me having to call them endlessly, I finally got through to someone, who confirmed that I need to speak to the insurance department to finalize the claim, however, the department they put you through simply keeps cutting you off. I even got someone to escalate the call so that they can call me back, but still nothing! This is not how you do business guys. Our company is one of the largest in the country and if this is how you treat your corporate clients, I shudder to think what poor level of performance the single client on the street is getting. <br> All I need is 30 seconds of SOMEONE at MTN insurance's time to talk to and settle the claim. Is it too much to ask to just do the work you are employed to do, let alone go above and beyond your client's expectations?<br> I suppose your response and manner in which you deal with this incident will determine the answer.
