Poor service regarding the installation of dash cam

Hi, I asked you to call me on tuesday last week, I am very upset and you are offering me extremely poor service, I asked last week monday for the installation of my dash cam unit on Friday 17 April 2026 at 14:00, but it did not happen on that time they scheduled it for 8:20 without my knowledge, on tuesday I asked an agent to call me and received a message which noted

"Good day Please be advised that you will be contacted at the requested time.", which also did not happen, on Friday 17 April 2026 I called the agent early in the morning to get this sorted and once again they moved the appointment to 14:00, at 14:00 I then called the Customer care line to follow up, but they informed me that my appointment was moved again without letting me know or asking if I was available the Agent i spoke to then let me know someone would call me to arrange a time and date, but no one did, so I am very upset and will resort to posting a review on hello peter if this is not sorted
