Harassment by Capitec collections

It has been months that I have been receiving phone calls any time of the day, but several times a day for a Elizabeth Ndwandwe. It does not matter how many times I tell the persons that are calling me that I don't know this person and that I keep on telling this every day for the last few months, they keep on phoning me. Today when I asked to speak to a manager about this, I was told the manager is not available. Then I requested to have the name and email address of the manager and I was told if I have an issue I must go to any Capitec branch to lodge a complaint! How extremely arrogant that is! They phone me on my number but I must go into a branch to lay an official complaint??
