Pathetic customer service

Absolutely pathetic customer service. You see a deal on the website that's been advertised and when you call in for an upgrade you told "its not for you only certain deals will apply when you upgrading"so why is it not stated that its for NEW LINES only. On top of that you get an agent that absolutely rude to you that is of no help. Is that the way telkom does business. I have 4 contracts with you guys clearly if this the way I am treated I'm sorry I rather go to another network that would appreciate me as a customer. The attitude, call conduct and professionalism is absolutely disgusting. When you ask to speak to higher management or supervisor that can assist you, you then get the run around where you constantly being transferred to another department and you still don't get any joy and your entire break has gone. I am at a stage where I am actually fed up. Its business that I am giving to telkom but it seems that I am asking for a favor. I deserve better.
