Useless customer service

My daughter banks with Absa bank. She went to Spain on a study visa and i had signing power on her account. She encountered a problem with extra money being debited from her account. So i contacted the call centre. They were absolutely useless at the call centre. Then again an extra amount was debited this month. So I called the call centre again. The lady asked me to hold and tben the call was cut. I call again same story the lady asks me to hold and tbe call was cut. All in all the time i spent trying to get this query resolved took an hour and half.on the phone. In the end i just agreed to pay the requested amount still not sure why.
