Caller: Debt Collector s

My ex house mate used my phone number as a contact number because he didn't have a number of his own.
That was 6 years ago. I am still getting phone calls from these jerks everyday despite the fact I have told them repeatedly it's not his number....
They are relentless. This behaviour should be illegal.
I got a second number just for family, somehow they got a hold of that too and they bombard me with calls on both numbers now.
Not impressed at all.
