Misleading

I am absolutely appalled by the service charge I incurred when I requested on the 03/07/219 for a transaction history from 25/06/2019 to date. The consultant advised me it will cost around R3.46. I checked my account today and I was billed R51.00. I called the call centre, spoke to Angelo. He wanted to put me through to the agent I spoke to the day before in order for her to sort it out. What happened to taking ownership of the call?? I then asked to provide me with the correct fee charge for a transaction history, he placed me on hold for 10 minutes and never came back to the call. Please check my last call history with these two agents and get management to sort this out
