Fibre-to-the-home billing woes

I migrated from a Telkom Simple ADSL service to Telkom 10 Mbps 50GB Fibre package. The installation was done within 7 days from signing up. Great service there Telkom.<br> <br> Roll forward to receiving my first bill after installation - what a mess!<br> <br> Both packages have got a fixed monthly charge so the maths are reasonably simple to do in terms of what should be billed. Not so for Wendy at the Call Centre when I called them today at 09:04. She does not see anything wrong and on top of that does not appear to know what the said monthly charge should be for the new service.<br> <br>
