Promises not kept

Ive asked for a installation and it was confirmed with the dispatch department that there will only be there UNTIL 11:00 in the morning and was confirmed that the tech should be finished before that time. The tech called just before 11:00 and said the install will tech +- 2hours. That time was was to late and then was told some will be coming the next day. When I called them nothing was updated and I need to call every time to receive any feed back on what is going on. Each note that I give to them they do not update on the system. If this is not installed by 13/12/2018 on ordernr ********** 20 Iam want all my money back and Telkom can get their bonus money from other people the will wait for **** service.
