Poor service and communication

I joined car tracker on the 17 July 2023 and they promised me that a technician will do the installation on the 25/26 July at my workplace.

No show up until they called me yesterday to say that I have regected their calls on the above date which is a lie they didn't contact me.

No problem, we reschedule a new appointment date for today morning at 08 am which they didn't show up. I had to call them, the consultant are so rude as they promised to call the technicians and get back to me but dololo. Mind you I called twice today with my airtime. What ****ed me of is that my whole Saturday is cancelled because l am waiting for a No Show technicians and no one is commutating with me on the way forward. Why is it difficult for your consultant and technician to communicate with clients.
