Hung up on and not assisted with Query

My Fiance has contacted cellc customer care with regards to a query relating to a contract I am using, we paid for 50minutes of call time and 1 gig night data and 1 gig day data. We were only given 30 minutes of the call time though we were charged the full amount. He just wanted to know if we were correct in our calculations and she told him that we get charged minutes for the data we use and sent us the statement for Feb but he was querying for March when he complained to her that she did not seem to have the correct training she was silent and hung up. He called back and was assisted and was provided the correct information there after. Palesa was incredibly rude and unhelpful and gave false information to a query that could have otherwise been resolved within minutes.
