Damages to my central locking

Car track was installed into my car on June 2021. it was a full new installation. in October 2021 i have noticed that my panic button was not working i called them back and told them my panic button is not working but no has called me back after calling them a few times. only in March 2022 i took my car to Cartrack New Germany so get it fixed. they fixed the panic button but damaged my cars central locking. my car does not lock with the remote. i called them back and asked them to fix it. they told me i need to take my car back to the dealership and get it fixed. i am so frustrated that i want to cancel my Cartrack but they said i need to pay R2600.00. i am still paying my Cartrack fee every moth. i will be calling my insurance company and inform them of damages done.

i need them to fix my car as they where the only ones that was working on it.
