MTN rude contact centre agent

My husband got 5gb anytime data on his phone that valid for 24hrs that he didn't purchase. The bundle eventually expired and when he tried to recharge airtime to buy more data, he got a message from XtraTime saying thank you for recharging. He didn't buy any XtraTime bundle! And when he called the MTN contact centre, the agent was more annoyed that he called than concerned with resolving the issue. He even told my husband "and stop clicking things on Facebook" as though he is a child. I think it's time to change network providers.
