Cartrack - horrible service

I would like to complain starting from last Monday. I bought a new car and phoned Cartrack to ask for to remove the unit out of the old car and install it into the new car while both cars are still on the same premises. I was told it is not possible (without a valid reason) and re-installation will be done on Wednesday. Wednesday came and NO ONE pitched or contacted me to reschedule I had to phone again, same happened until Friday then the technician was late and took almost THREE hours to do the installation while I had to make other arrangements to pick up my daughter from school and had a function to attend and missed a appointed because of this. When he was done, my car's driver carpet was dirty (remember this is my NEW car) and the radio was set to a other station and I could tell the car was on and my aircon running the whole time - I know this because I check my fuel consumption regularly. Then I thought ok, Cartrack you cannot disappoint me anymore...but no, you did. Yesterday, while I was in church with my family my phone rang like three times, when I saw it was Cartrack I when out of the church and ran to my car thinking something was wrong, but nothing, then I answered my phone and the lady told me my account was in arrears! I almost exploded. The R870 for the installation went of last week and my monthly debit order (which was apparently not paid according to her) went off on the 1st just like any other month for the past 2 years. This past week I was so disappointed in Cartrack, if I was not binded to a contract till June 2024, I would change to Netstar or any other company. Never in my life have struggled so much with service. Cartrack have NO respect for other people's time - and calling me on a Sunday while I am in church was just enough.
