Telkom are charging me an exorbitant, nonsensical fee for a line-speed upgrade when they never used to. Bunch of *******.

Last month, I decided to upgrade my line speed, which is something I had done a few months ago, too, without any issue with the payment. My package was simply upgraded from 10GBs a month to the 10mbps uncapped deal, and I was simply charged the exact amount per month of the 10mbps deal. Last month, which was 3 months after I had upgraded to the 10mbps deal, I decided to upgrade once again to the 2TB package. Everything went as planned, and my line was upgraded. I was not told about any early upgrade fees. This month, to my shock, I opened my invoice and saw that I was being charged R3000+ for the upgrade. I phoned in to ask what the hell is happening, and the agent I spoke to was not able to answer why I was being charged this when I had previously upgraded the connection without incurring anything like this. I am going to pull authorisation to debit my account, and Telkom can forget about ever doing business with me ever again.
