Worst tracker company

I have a tracker installed into my car, but policy under my husbands name because of the car insurance being under his name as he is driving the car. I phoned cartrack yesterday to change banking details as the banking details on there is under my name and I'am currently on maternity leave and not recieving a salary. The person I spoke with said they can't speak to me as I'am not the account holder of the policy and that he must send an email to them with my details to say he gives me permission to speak to them.. So I told this person that my husband works and sleeps most of the time because he works shifts and that he did send an email before that they can speak to me. But apparently that email is gone. So my husband took off work yesterday to speak to cartrack and to cancel the tracker because we anyway want to sell the car, then they tell us we need to pay a cancellation fee of R1700...that is just ridiculous! So we asked them to send recording of verbal contract and then he gave them my details so that they can speak to me from now on. Today I phone to change bank detials and they still have excuses of we need to fill in forms and they still need to speak to my husband.
