Rude and unwilling to assist consultant

So today I took my car for a service, I forgot to inform car track that my car was in for service. While they were busy with my car one of the mechanics asked if my car had a tracking device, I said yes and he said "well we've taken out the battery in your car and we are surprised you are not saying anything " I responded by saying I haven't received a call from car track yet. Worried that my tracking unit could be faulty I called car track track to test my unit, I got through to the most rude consultant ever. I asked her to test my unit and she asked me for the registration number, I gave it to her and she said her system was slow. While waiting on the call I asked when last the unit was tested and she snapped and told me it was not car tracks responsibility to test the unit but mine and said all this is there on my contract, I responded and said she was being rude and asked her for her name and surname, she then said her name was Sbongile, I asked her for her surname then she out me on hold and then hung up the call. I called again and asked to speak to the supervisor, the lady then said I got through to the wrong department but said she would communicate with the relevant department and give me feedback. While waiting for the feedback the call got cut off. I haven't received a call back from car trac. I'm paying for their services and It's frustrating to not get assistance and be rudely spoken to like you are not a client. Call I get a call back from someone superior about this
