Daily harrassment from Nedbank, not even a client!

I am not a Nedbank client, yet for the past month I’ve been receiving daily phone calls—2 to 3 times a day from various Nedbank agents regarding my ex-husband’s financial matters. I informed them I am divorced and requested my number be removed from their system. Despite this, the calls have not stopped. I block the numbers, but new ones keep coming from across South Africa as the agents apparently work remotely. This has continued even after I submitted a formal complaint to Nedbank's Complaints Department last Friday. I was told it could take up to 21 days to resolve. In the meantime, I continue to be harassed daily. I followed up again yesterday, only to be told again that I need to wait while they "investigate." This is not my issue to deal with. It is extremely disruptive, especially because I need to keep my phone on in case of emergencies. After a month of repeated, unwanted calls over a matter that has nothing to do with me, this has become beyond frustrating. Nedbank, please take this seriously and remove my number from your systems immediately. I should not have to endure this level of disruption for something I have no involvement in.
