Summons for my deceased Mother???

My Mother passed away on 09 September 2020. She had a Vodacom account. I phoned Vodacom to inform them that I need to cancel the contract. I received the deceased account management form and completed it with all the documents requested. Now, today, I received a "Draft Summons" addressed to my departed Mother, stating that she will be handed over for debt collection. Now, South African people!! How do you want me to further explain to you that my Mother is no longer with us. She passed away during an extremely difficult time. WHY, WHY WHY on WHAT don't you understand about death? She can not pay as she passed away. I did gave you ALL the information requested together with her Will. At this stage, it shows me how *********** your company is.
