Harassed by DirectAxis phone calls

Extremely angry at the number of phone calls I have received from DirectAxis call centre people , they have been calling me every week with out fail for over a month now. To make things worse they LOOKING FOR MY MOTHER (I'm not a client of theirs, and don't stay with my mom) who is under debt review and her lawyers are on the matter!! They have her phone number, I've explained what I know on my side .

Lost my cool today when they called me AGAIN when the last called me 5 days ago. I've asked them never to call me again but clearly no one cares and they just hang up the phone in the middle of my sentence.

HelloPeter I hope you can help me, or advice me on how to launch this compliant further. No one should be harassed to such an extent even if they did get a hold of my mother, she doing a very best.

This number that always calls me. + ********** 4297
