Harassment

Good day<br> <br> My daughter has been receiving calls from ***7 every single day for months now. When we answer there is no reply. When I phone vodacom I cannot get through. I googled the number and the amount of complaints that came up is scary. From ***** to sim swaps. How can vodacom allow this to happen? I am so glad I changed my contract to a fixed amount and that no bank accounts are linked to that number. This is pathetic, to say the least.
