Bad service

The incorrect phone was blacklisted by mistake because I had 2 iPhone 13's that are the same. I have been trying to get the correct phone unlocked and vice versa but Vodacom insurance tells me there's nothing they can do, even though I'm paying for 3 devices. I've honestly had the worst year with them, when you call or send them emails, they don't respond I will not be renewing any of my contracts after being with them for years.
