Frustration

My husband pas away 28/10/2020, I contact Vodacom to inform them, and ask them what I must do to transfer ownership and bank account for the payment in the future on debit order. The contract consist for many years of my late husband's cellphone, my own and also a fibre contract that was activated in the middle of September 2020. I was informed to phone *** that was for the fibre, the lady on the other side said I must go to a Vodacom shop to do the transfer. Well this morning 10/11/2020 I suddenly realize that everything was suspended although it is paid up to 30/11/2020. The lady in the shop took all my papers and typing on her computer, I could not see what she was doing but realize that she ask the lady next to her every time if this is right, I was told that the lady for the fibre is not there and I must come back on the 12/11/2020 because the payment that was deducted on 2/11/2020 will only showing then. No phone no contact with anybody in a time that I am very vulnerable . The fibre lady phone me later and said I do not need to come in on the 12th I must phone *** I tried four times and was cut of every time I try to explain my problem. In their app there is nowhere any information for deceased queries. I really am so frustrated and don't know if my problem will be solved on Thursday.
