Passing the buck

When attempting to buy Telkom Mobile airtime online on my Standard Bank mobile app I accidentaly left the default service provider as Cell C and then entered a Telkom Mobile number. Standard Bank informed me that this money was paid through to Cell C and they would have to reverse the charge. After clearly explaining my query to the Cell C rep several times he ridiculously tried to first solve the query by going into my other Cell C contract account and then informed me that I'd have to resolve the issue with Telkom Mobile which is clearly not the case. It was simply easier to just pass the buck and not try to understand the issue or pass it on to a supervisor or the correct department who could help me. I even told the rep that I'd be willing to have the airtime loaded on an alternative Cell C number instead of getting a refund as the number entered upon purchasing the airtime is obviously not existant on the Cell C network.
