Is Vodacom acting *******ly ?? innocent person harassed

Vodecom have(*1) engaged or have a contractual arrangement with a group of '****s(*2) 'who harass my wife and I daily with calls on our landline demanding to speak to a relative who they claim owes Vodacom money. The relative who has immigrated claims to have proof that his/her account is fully settled and we are not to divulge personal information to these unidentified people verbally over the phone. We have frequently requested if Vodecom have an issue with the person to contact that person on the e-mail adress that they have for that person. (Vodecom have used this adress and sucessfully communicated with their ex client, in vain. Vodacom care center (call 2H40 pm 26-1-22 recorded for quality and security purposes) have said that until the relative can get the Vodecom accounts department to acknowledge they incorrectly have engaged these ****s we will continue to be harassed for an account which we are in no way liable. Surely this amounts to some ******** activity on the part of Vodecom or their agents hence term ****s(*2) ? Even if the relative dose owe Vodecom money with what authority has Vodacom divulged my land line number to these agents ( difficult to block thes calls ( Poppi act?) and surely if Vodecom know my number they have my adress. I have an account with Vodecom. These '****s' know the relative is overseas and instructed Vodecom to contact him/her via email. Why do they daily harass my wife and I? We may even have paid money we don't owe for peace but we don't get that option. If Vodecom believe that I in some way owe them money or have stood surety for someone else's debts could they not engage with me in a more civilized /legal manner to adress this issue via e-mail or post? The ****s will not disclose exactly how they are related to Vodecom or give any relative detail BUT THE CALL CENTER HAS ASSUED(*1)ME I WILL ME CONTINUED TO BE HARASSED BY THESE PEOPLE, AND THIS WITH VODECOM SANCTION Help!!!
