Live Chat Consultants dropping chats

I have received the worst service ever from Telkom. Absolutely putrid to say the least. Firstly I spoke to a lady called Lindiwe who advised me that Telkom had a "first in first out policy" when it came to data, but this policy has not been app**** to my account my monthly data has expired but I still have data on a bundle I bought the previous month and that expires before my monthly data plan - this has completely messed up my account. When I contacted Telkom via live chat I spoke to a koketso maswanganye who hung up on the chat this was on the 10th of November. I contacted Telkom again via Live chat to resolve the matter, I spoke to a Rulani who didn't even give me time to explain he or she gave me a standard response and also ended the chat. I disgusted with my treatment from Telkom and it's employees. I will be taking the matter up with the consumer commission on Monday, hear me now Telkom I will be your worst nightmare.
