Installer not coming out

Good day,<br> <br> We ordered a line and everything went smoothly up until the installation date. on the 23/07/'15 we received a text message that an installer will be dispatched on the 29/07/15 , I put in a days leave so that I could be there to receive the installer. At 15:00 I called the 10210 number and they told me that someone is still on their way but no one pitched, the next day we logged the problem and we received a text message with a new installation date on the 03/08/15, again I put leave in but no one pitched. The 04/08/15 I called again and they gave me the number of Jaco Douglas and asked me to arrange the installation with him. He told me that its not procedure and that he tried to contact us but could not get hold of us. We received almost a dozen sms's but the day he calls us he calls on my alternative number which the call center got wrong . Regardless that I find it strange that they would do that, when I call the 10210 number they keep giving me Jaco's Number. The office number just rings and Jaco ignores all my text messages and all my calls. <br> <br> I keep taking days off to have this installed but no one comes to the party.
