Door lock

We had a tracker installed on the vehicle and after doing pre checks on the installation of the tracker it was discovered that our drivers door lock is faulty. It does not function properly. After lodging a complaint with Netstar we were promised it will be paid for and fixed asap but the latter never happened as they discovered the price by Barons would be too much. The technician did log the call and we have been contacting Net star constantly and the technician did advise it will be fixed by them. We have also requested the tracker to be removed but nothing is happening. The fact that we constantly calling to have it sorted out is pathetic
