Useless Vodacom!!

My father passed away about 5 weeks ago and I have been trying to sort out his account for the last 3 weeks. I phoned Vodacom only to be told that there's not much they can help me with until the Vodacom Stores open. Well they opened on 1 May and I went to the Vodacom Store at East Rand Mall today only to be told that I can not transfer the account to my account as they are using different systems and my account needs to be moved to the new system but they can't do that because of lockdown. I then tried to open an account for my mother only to be told that I require 3 month's bank statements which is impossible as my parents had joint accounts and that account is frozen. So right now there is absolutely nothing that I can do. It's really simple, just transfer the account into my name. Not my problem that your systems are not capable of doing that. Absolutely pathetic Vodacom!!
