Poor poor poor customer service and very suspicious billing

Telkom consultants, both on the telephone and on the live chat either hung up on, or ended the live chat when I asked for help on a matter or asked to be referred to management.

I set my spending limit on my data package at R0 to ensure that I do not go over my budgeted amount. When my bill is much higher than budgeted for they tell me I spent out of bundle and am liable for the account. I want them to refer back to the recorded call of when I took out the contract, was explained that I could set the spending limit at R0. They hang up on me or end the chat abruptly. I have screen shots and names of these consultants.

I am so tired of incorrect billing issues- the last two months have been by far the worst, but the customer service has been ridiculously poor.
