Telkom fibre contract sudden increases

So I just signed a 12 month fibre to the home contract for R549. I was not informed that the amount can be increased at any time during the contract.

Telkom suddenly increases my subscription to R619

I call the agent who signed me up - she says call 10217 (Julie - *** - ***)

Called 10217 - a lady with a really unhelpful attitude refused to give me a reference to lodge a case with the ICASA ombudsman. Agent from Durban accounts was Pumla Ngobele. She says it's in the terms and condititions so there is no dispute.

I want a reference so I can take this up with ICASA. She point blank refused - saying I should go back to the store who signed me up. (That's Julie - who told me to call the (un)help line

Telkom is living up 100% to their rotten reputation.
