Welcome to Vodafone Community
I believe this is very well off topic, but the vodafone chat has been great for me in the past to get in touch with any sort of matters, but it's around 4 days I'm trying to use it without luck. It's either always busy or I'm not getting assigned to any operator.
Have you noticed anything like that?
I'm really sorry to hear about the trouble you've had getting in touch @r4w and apologise for any inconvenience this has caused. Did you manage to get everything resolved in the end?
If not please don't hesitate to get back in touch and I'll be happy to help in any way I can 👍
