Old owner of the number is the most wanted and I don’t know this person

Your network is good, I just have a question, is there a way of generating new contact numbers for your new clients? I’m being called by MBD and all other companies looking for a Mr mxolisi ntombela I don’t know!! I bought a phone 4 months ago and boom I have to explain myself to these providers simply because you regenerate old numbers and give them to new customers. as South Africans we are already having issues with direct telephone marketing services we did not give consent for and now we have to inherit people’s frustration from debt collectors simply because we signed up to be your customers?
