Terrible debt collector and legal practice

Very unprofessional legal firm and debt collector. Sending legal threats to obtain judgement to attach property to 3rd parties of deceased person that they claim owe Vodacom money. Legal practioners and Debt collectors has no authority to contact or make threats to 3rd parties or family who they claim owe money to Vodacom. As for Vodacom, they should keep proper records of account before handing a file to attorneys. Especially if the account was very old and closed already. Next step would be to report them to the Law Society.
