Annoying calls from collections

I am very annoyed by the constant phone calls I get from Cartrack just because of a returned R100 debit order. A simply message or email could have been enough and the issue could have been sorted. Today I received like many calls making my work difficult and actually a little bit embarrassing to my fellow workers like I’m owing thousands.

I use a different account for this debit and didn’t know debit order was returned this month. This model of customer interaction should be looked at because it is annoying. I have paid your R100 jeez
