Bad/No communication

I was phoned by dstv last week informing me I qualify for a price lock promotion so I accepted the deal and upgraded to the premium package, the lady advised that she would arrange for installation to take place Monday 06/02/2023 I said I wouldn't be able to do it on that day could we perhaps do it on Wednesday (today) 08/02/2023 she agreed, I made my wife to take off a day off work today in order to accommodate the installers I was waiting all morning nobody appeared or contacted me, I decided to go online and track the installation and I see that multichoice agent or someone changed the date to the 14th of February 2023 without giving me prior notice, this is really bad service from multichoice and an inconvenience I'm no longer interested in this deal
