Poor Customer Service

I logged a call on Monday and assumed that my issue was clear. I received reference number and 2x SMS confirming the call. On Monday I was asked to call back after 3 days for a status update. <br> <br> Called today. First Karabo hangs up on me. Second attempt .. Thulisiwe first says the reference number that MTN gave me was invalid and did not exist! WOW! Then she finally finds info on the query, but proceeds to ask me again all the questions I'd already answered on Monday 8th Feb! <br> <br> I asked to be transferred to her supervisor .. 10 minutes later I'm still waiting for the supervisor, and she puts me on hold. No update. Nothing. Is this what you call customer service? <br> <br> Unacceptable!
