Telkom - Teriible customer service!!!!

I went to Telkom on the 04/05/2019 to upgrade my ADSL line from 4mbps to a 10mbps line. I was told it would take 7 days.

It has been 2 weeks already, my line has still not been upgraded after numerous calls and visits to Telkom. I'm lucky if I get 0.8mbps. All I get told when I phone is it hasn't been completed yet but they are going to send an email.

How long could it possibly take to upgrade a line!!??

Telkom has terrible after sales service and I would not recommend anyone to sign up with them.
