Can not get anyone to contact me

I really want to get out of my LTE contract as fibre is now available by us. But I got an e-mail to say I could get double my data without extending my contract period. So I go into the Telkom store to do the change. They tell me it is a special department that only does out going calls, they will mail them to call me back. One week later I have heard nothing, so I phone sales. They tell me they have sent a mail, I will get called back. One week later I try again, I get told the same thing and a manager will be included in the communication.

I can’t make any progress with Telkom. I have a mail saying ”upgrade to a higher data plan, without any cancellation fees, device fees or change in your contract period.” With absolutely no way of effecting this change!

Even this post is going to get a generic auto response so Telkom can say they are a company that responds.
