Overbilled without being noticed

Hi all.

I have a situation here with Telkom's Wireless landline which needs to get to attention of Telkom, and I will push to get it to the top of their management if needed.

Basically I visited someone who's mother is a pensioner - they let me use the wifi feature. - I was under the impression that they had some sort of data bundle attached, and only used it for light internet usage.

There was no large downloading that occurred.

The largest downloading that happened according to the phone bill was 1156.0044mb

Fast forward to today, I got a phone call from them saying they got a phone bill for nearly R5000.

I find it absolutely ridiculous that the bill was firstly able to accumulate without someone, or something at Telkom realizing that, and then cutting off the internet or their phone service completely.

What has happened to others in the same situation?

She is a pensioner here - I have offered to settle the bill in it's entirety if needed.

I have told her not to worry, I am on it. I just hope this gets sorted.

However Telkom should really have things in place to ensure this doesn't happen again.

Others should please take this as a warning.

Thanks
