Poor Service by Angelina in Finance

I just called telkom to get clarity on my billing. I dialed the billing department and spoke to Angelina. I explained that I just took 2 contracts with telkom and asked her to explain the debit order that went through my account because it was more than what I agreed on. She asked if my contracts were mobile or business, and I rep**** to her that its a data contract as well as a mobile contract. She then said both these contracts fall under mobile and I should speak to the mobile department. She then disconnected the call without any warning, which sent me back to the main menu!!! I am really disappointed about the service provided by Angelina, she is inconsiderate and is a huge liabilty to the company. I held on the call for more than 15min trying to get through, and once I'm through, this is the kind of service a new client gets, on his 1st interaction with Telkom after signing 2 24month contracts? Guys, do you really want and care about my business??
