Be careful of these ****mers

This company has been harassing me since 2020. If I say harassing I mean 5-7 calls a day starting at 06h30 in the morning and last call is at 19h00. I am being called on both my cellphone numbers and they call me at work as well. I am being called Monday to Saturday every day since April 2020. I lost my job due to covid and my debt was written off by the bank but they have been harassing me non stop. I don't know what to do anymore as I'm at the point where my boss is asking why I'm being called every day by multiple people from the same company. I have probably blocked close to 500 numbers already. Every day it's a new pre paid number that they call me from. Never the same number twice. Be careful of these ****mers!
