3 appointment confirmations for wrong day!!

Having app**** at a Telkom shop in Sea Point I was told that Telkom would contact me with a designated appointment day to activate/install my line. Following this I was pleasantly surprised that I received a text message to confirm 13/04/2015 as my appointment day. A few days later a representative of Telkom called me to remind me that my appointment day was 13/04/2015. On Friday Telkom sent me another text message confirming that an agent would visit my house on 13/04/2015. Today, after having taken a day off work, nobody arrived from Telkom. I went to [URL Removed] to reschedule the appointment and, to my utter bewilderment, read that my appointment had actually been scheduled for 11/04/2015. This is ridiculous!
