Poor service from Vodacom

I am so.. disappointed in Vodacom. My husband passed away in March 2023 I went to a Vodashop in April to transfer my number from his account and took out a new contract on my name. Since then they bill me still under my husband's name. Since last year I have spoken every month to a different person working there - nothing is happening. I can not claim the cash benefit because my number is still on my husband's name and I am worried that Vodacom will close my number then I am without a phone number. How can it be so difficult just to transfer my contract (I took out a new one on my name in April) to my name!! It is a very difficult time for anybody who lost a love one. Why must we struggle so... much just to get a number transferred to your name!
