Abuse of Power and in violation of POPI and PAIA

I received a call twice today from an *** and when you answer there is a 2 minute pause then the phone rings on the other side then you find out it is Norman Bisset & Associates. I asked the lady to call me back on with her first call in 15 minutes, I then received a call 3 hours later and I was in a meeting so i could not answer. At 19h00 tonight the very same number called on my husbands phone and i cut the call. My concern is are we not protected by Access to Information Act and the Popi Act? They managed to do a trace on me to get my husbands number after a 2nd attempt today. This is a serious violation of my privacy because if they are looking for me they should keep on trying, i don't sit around waiting on calls, i am also trying to work. I called the number again and it clearly states their operating hours is from 8am to 16pm so why would they call on my husband's after 19h00 at night. The best thing is that my husband's number is a work number so these debt collection companies are abusing their power by accessing a person's private information to make a collection and earn 10% commission on the collection. I have an idea who might have listed me which is tracker as I stopped the debt order as I never received any form of communication from them about my contract and not once did i get a call from them in the three years that I apparently. Norman Bissett & Associates Group should know their place as a Debt Collection company and not abuse their access to Credit Bureau Information to obtain alternative contacts without my consent to try and get hold of me, who ever handed me over should have provided them with office number, cell number and email but they tend to only use a cell number and after the 2nd attempt they access my husband details let alone send me some form of communication that I am being handed over and up until today I am assuming it is tracker because they called me and I gave them my side and I am still waiting on them to send me my signed contract. These debt collection companies access should be revoked from the credit Bureaus as they are abusing their power. I will also report them to the NCR for violation of privacy as they are bound by a code of ethics if they are registered with the NCR. This utter bull dust.
