Bad Feedback

My handset was collected from me on the 16th of February 2016 bound for repairs via MTN Insurance. After about 3 weeks I called MTN Insurance for an update and I was told on an excess fee I had to pay. I paid the fee and sent through the proof. I called back in and a lady by the name of Nomonde told me the phone was repair and that she has requested for it to be released and sent back. 2 weeks later, still no phone; I call back only to be told the phone was sent back to the supplier. I wait another 2 weeks, still nothing. I log a complaint and am promised 5 day response, nothing happens. I call back in and ask to speak to a supervisor and I told they are in a meeting and they will call me back, still waiting. A month of back and forth logging calls, sending emails, no one calls me back. Both MTN Customer service and Insurance, emails sent, calls logged yet no one is calling me back. THIS IS THE MOST \PASS THE BUCK\" nonsense I've ever experienced. If Customer Service can't help, where does one go. "
