Ignoring my request

African Bank collections call centre phones my office at least 3 x daily to speak to one of our factory employees. Although I have explained to the supervisor that he works in a factory, and can therefore not be called for personal calls, they still persist to phone this number. If you do not stop with this, I will contact the Banking Ombudsman and lay a formal complaint. I trust this will be the last of it. You can contact me for the specific person's details to remove the work number from his profile.
