do you care about happy customers?

I have been an MTN customer on contract for 15 years and my monthly account is not small!<br> I am trying to upgrade 2 of my 3 contracts with MTN over the phone.<br> First of all, it took me 50 minutes on the phone!<br> Secondly, a security check was done at the end, and then I was just told, you have not answered some of the questions correct, please go to a store to upgrade.<br> Really? You must maybe check the questions and answers in you system.<br> Then I tried to speak to someone that can help clarify the situation - after jumping through a couple of hoops and holding on for a long time, the call was just dropped.<br> Obviously I am frustrated, but mostly I am wondering - Do you care about keeping customers happy?<br> Especially loyal customers spending a lot of money on a monthly basis?<br> <br>
