Failed to keep appointment. No comeback

I queued for nearly an hour in the Lakeside store to book an ADSL line<br> <br> The appointment was set by Telkom - confirmed on both sides by sms for Tuesday. I arranged to have someone t home all day from 9am - 4pm.<br> <br> No-one turned up. Two days later, I still have no information<br> <br> This is a very poor show - even if they do have the monopoly on ADSL lines, there is no excuse for failing to keep appointments or even to notify the customer if there is a problem
