How the deceased are harassed

In July 2020 both my parents passed on.My mother Mrs Antjie Jardine held a account with Makro on the 17 August 2020 i forwarded the death certificate to not only Makro but other institutions my mother held credit with requesting closure of these accounts.Since the 6 January 2021 I had been recieving daily calls from MBD to recover debt insisting that the account had been handed over to them when explaining the situation to the them they daily insist I forward them with the death certificate.I made it clear that my mom held credit with Makro and that I am not obligated to forward the death certificate to MBD as they are debt recovery services and not credit providers.On the 18 January 2021 I forwarded a letter to MBD as proof that i had sent documents to Makro and that Makro should never have handed over the account of a deceased person to MBD i told them that their problem now lies with Makro and they should approach Makro for the death certificate.Since the 19 January 2021 MBD has continued to phone and harass me for documents which is truly unprofessional and shows extreme ignorance hardly six months after my mom had passed on Makro together with MBD have contributed to our pain and suffering.I will now be approaching legal counsel too seek advice on this continues harassment and contribution of pain and sorrow
