Useless contact centre

Everytime a device is cancelled telephonically I am debited but the account is not closed by your finance department.

I keep making appointments to transfer tracking devices but they're not honored and the accounts department cannot tell when i gave instructions for these requests... Are you not using the same systems for other departments to see the same requests? Car Track is very unprofessional and I have a good mind to just terminate everything with them because the contact centre is useless!!!! They cannot get anything done. So dissapointed.
