In Summary:<br> <br> Booked an appointment to have a voice line installed, appointment confirmation received, technician never came.<br> Phoned, was promised that a technical manager would call, never called.<br> <br> Booked for a SECOND time, confirmed, tech never came. Called, was promised a call back, nothing.<br> <br> Booked for a THIRD time, confirmed, tech never came. Called, was promised a call back, nothing<br> <br> Booked for a FOURTH time, confirmed, tech never came. Called, was promised a call back, nothing<br> <br> Any suggestions my good friends at Telkom?
