Very poor service from the get go

I did an online request for both of my vechiles on the 28th of September 2022, a staff member contacted me within a few minutes, which was great and my contract was done electronically via telephone, then it all started going downwards from there on, 3 more staff members contacted me to sign a contract after already being signed. The first staff member told me that both of my instalations can be done at different locations, I just need to inform the installtion team once they contact me within half an hour. Just before COB on Wednesday the installation team made contact with me, sttai g that both my vechiles need to be at the same location for them to install the tracker units and gave a date for Monday 03 October 2022, I then told her it will have to be after 5 pm since this will be the only time that both the vechiles will be situated in the same location at the same time, she then asked if I cannot leave the vechiles at home during the day, on which I rep**** "No because I need to use my vehicle to get to work and the other vechile is used by my partner who also need to get to work using the vechile." then she rep**** that installtion will be done on Monday 03 October 2022 after 5 pm and someone will contact me an hour prior to installing the units. On 03 October 2022, I received a call from the installer, just before 10 am, asking if I am available for him to install the units. I told the person that I have requested the installation to be done after 5pm. The same person pboned me back just after 10am asking if I am available for the units to be installed, I once again rep**** that I have requested for the installation to be done after 5 pm. The person responded by saying that someone from installation will be in contact with me soon. Trying to get the matter resolved, as I only have 7 days to submit the installation certificate to my insurance as the one vechile is financed, I phoned Cartrack and requested 5 to speak to the installation team, the call dropped after 5 minutes, phoned again requested 8 to speak to an operator, customer service answered the phone and said that she will put me through to the installation team, the call again dropped after 5 minutes. After waiting the entire Monday to hear anything from Cartrack, I get a call just after 4 pm from customer service, the same person from customer service contacted me that I spoke to previously, asking if my units have been installed into my vechiles, I rep**** that I am very unhappy with the service and that I only have tomorrow left for the units to be installed, as I will have to submit my installation certificate on Wednesday for the Insurance, and have been waiting for someone in the installation team to contact me to arrange a new installation date and time, she then went silent and dropped the call without any feedback. The service is beyond poor and hope for this to be sorted and installed tomorrow, or I will have to use another tracker provider.
