Nedbank harassing me.

Good day, Nedbank call me every day on my Skype number and ask to speak with a specific person unrelated to me. I begged Nedbank to remove my number from that person's profile as they are wasting my time and basically harassing me. I called the number calling me and they found my number on the other persons profile. I tried to resolve this issue a few times. The caller's promised to remove my number but they were blatantly lying.
