Cartrack accounts department

This is the second time I have to write here but it seems like this is the only way to resolve anything with Cartrack accounts.

They really harass customers. Even on a Sunday, late in evenings whenever completely unnecessary!

Cartrack for some reason only took half the debit order amount, why I do not know, now I am being harassed because apparently my account is now in arrears????

Yet, Cartrack should give me 4 free installments for references that I have been struggling with now for MONTHS!!!

PLEASE GET YOUR ACCOUNTS DEPARTMENT IN ORDER AND STOP HARASSING ME FOR NO REASON. I DON'T HARASS YOU FOR THE MONEY YOU OWE ME!!!
