Telkom fails to pitch once again

My order number is ***. I recieved word via sms that a tech will be installing a new adsl line between 07:30 and 12:00 on 2015/06/15. I spesifically asked for an appointment before 12 any day the tech is available. I have to go to work soon and if the tech arrives if I am not here it wil probably take longer to get a reaponse. This ia my 3rd complaint about telkom and the poor service delivery. I dont know what to do you have to pay and beg for service
