****mers that will not let you go!

This is the worst company from which to get tracking services. I requested the unit in my SOLD car be canceled, they ignored my emails and continued to debit my account. I called back only for them to give me a reference number and a settlement amount to be paid which I did pay. Now I received a statement of another outstanding R600 that needs to be paid. HOW am I having the account in areas when the settlement had been paid.
