Call centre harassment

Good Day Please help by removing my cell number from ‘Mr Mangena’s’ record. This is not Mr Mangena. This is Brad Bonner. I have been phoned by your debt collection company every day for the last 4 months! Despite me telling every person that calls and their supervisors, they still continue to call and SMS me! My number is *** The reference used by the debt collection company is ***

Please correct this urgently.
