Where is Vodacom ethics ?

So I upgraded my contract a month ago to the new Samsung S8 that comes with a J5 additional line with the sole purpose to give the extra phone to my 10 year old daughter. Only to find that the number that Vodacom issued for the additional line was recycled and was previously owned by someone the clearly had no financial common-sense. From the first day the line went active we have been bombarded by loans harks and debt collectors for moneys owned, combined with hundreds of SMS from all the big clothing retailers for outstanding accounts, to the extend that my daughter is now too afraid to keep the phone with her. Vodacom’s response to this was just that they cannot change the number for a top up package……. . So now I ask you, where is Vodacom’s ethics when it comes re-selling second-hand products? And Vodacom, do you want to tell me that your ETHICAL stance is this case is that you are in total disregard for the minor that now needs to use your second hand product? And that is fine that a minor gets verbally abused by loan sharks and debt collectors because VODACOM supp**** her with a second-hand product? I would love to convey that message to the press if that is your official stance. It’s been a month now since my upgrade, the local Vodacom store has apparently been trying to reverse my upgrade to re-issue a new number with no support from Vodacom itself, and still no resolution…..
