Telkom Technician not pitching

My son, residing with me, started his own IT business. He ordered a Telkom ADSL installation on the 20th of August. He received an SMS saying that a Telkom technician will be sent out of the 3rd of September to install the line. He never pitched to install the line and he received multiple messages from the 7th of September saying that his internet and phone number is ready for use! He contacted the call centre four times since then to log a complaint. He was given multiple reasons for the delay. He also received an SMS saying that he will be billed pro-rata from the 4th of September! He also messaged Telkom on Facebook and was told they will be in touch. He again called on the 14th of September. A helpful call centre agent escalated his call and said he must wait 24 to 48 hours for Telkom to contact him. Nothing happened!
