Telkom - sort out this mess!!

I informed Telkom on 25 August of the death of my husband sending relevant documents as proof. I received a reply on 27 August that they acknowledge receipt by the support team. A month has now passed and a account was sent to my late husband's email address dated billing him 1-30 Sep. I am not going to pay this account as you have been informed that he passed away on 14 August and I paid the August account.
