Unfair interruption

I was on hold for more than 30 minutes. When the call was finally answered, the agent tried to help me but when he was busy giving me instructions of how to solve my router problem, the call was cut off. I was out out airtime. I spent R150 worth of airtime on that call, and I did not receive a call back from Mweb when my call was cut off. Please treat your paying customers with kindness.
