No technical support to install device

In December i signed up for Telkoms new boltspeed wifi. In February i finally phoned because, although I had received all the hardware, no-one had come to install it. Eventually i was given a reference ***8 to get a technician on site. Another phone call on 22 Feb finally discovered that they claimed they had phoned and been unable to reach me. The call centre reactivated the call. On Thursday i received a text telling me my problem has been resolved. I phone this morning 14 March, to be told they couldn't reach me on my cell. We have now opened a new case, but clearly the technical division doesn't actually want to do the installations and just keeps lying to avoid the problem. Get on with it Telkom.please!
