Sipho is making debt under wrong contact details

My cell number was used by some one else to rack up debt and not pay. I have received messages from various debt collection agencies and other institutions for this person. When trying to contact MPOWA to ask them to remove my number from their database, no one assisted me. I got to speak to a human eventually who transferred me to collections department and then the call was cut. This happened 5 times this morning. Your reference number is MP_***0. The person who falsely used my number is named Sipho. I am not Sipho Remove my number from your database immediately
