Threatening people without valid reasons

<p>Good morning. My husband was looking for a loan some time ago. We went onto various websites but at the end of the day did not take a loan with any of the companies. This company is now sending us threatening messages every single day that they will issue summons if we do not pay R1 500. When you send communication back to them they just ignore you and you can never get through on their phone lines. What does one do about this?</p>
