Harassment calls and messages

Ackermans and dept collection Tenacity is the most *********** people ever.

I have spoke to both these companies on a regular basis due to wrong details that was given by an account holder.

I have sent multiple emails to Tenacity requesting them to remove my number off their system as the number does not belong to the person the are looking for.

I receive multiple calls and sms's from Ackermans and Tenacity and this is becoming harassment
