Vodacom has no respect for the deceased or their families

My mother has passed away on 25 September 2021. After enquiring with the local Vodacom shops on the process to stop her mobile account, we were directed to email ***. We did this on 29 September 2021, send the number***), My mother's ID and Death certificate as proof. We asked for confirmation as well. No reply was received. We have however set the Read receipt option and got a reply that the email was opened on 2 October 2021. Up to now no response was received to confirm the request. The monthly subscription is still going off the account and we can't stop it since it is a debit order. Since we have now followed process and Vodacom has not closed down and payed back the money, this constitutes *****, We will take legal council to our our next steps against Vodacom. The fact that this happens show that Vodacom's company value and ethics is non existing. We are dealing with the loss of a mother and now have to struglle with administrative mess purely because Vodacom seems to be to greedy to stop the account.
