My husband died and VODACOM treated me badly

PLEASE HELP. Does anyone know an actual HUMAN BEING in a decision-making position at VODACOM? Can you send me contact details? It has been 3 months since my husband died. Upwards of 12 in-store visits to VODACOM Stores; upwards of 24 hours on Call Centre lines; 7 separate submissions of all the relevant and required certified documentation; innumerable calls and emails to individual client service people. And the account holder hasn't been changed. My daughter and I still I have temporary sim cards and our old phone numbers are blocked. (we've had the same numbers for 24 years and 10 years respectively). Any suggestions very welcome.
