Failure to install an operation line

We app**** for Telkom' ADSL for our office on the 20th of February. They only sent a technician last week to come and install the line. We still do not have internet because the device is not connected properly by the person who assured us that we will have internet same day after installation. To top it off we could not get anyone to pick up the phone when we tried to call in yesterday. Now we are using our mobile phones Wi-Fi signals to do anything and everything. <br> <br> The funny part is that they have already sent us a statement for the line.
