Vodacom Roaming Doesn't Work!

I'm currently traveling abroad. When I left SA I made sure my roaming was activated. Got to Ireland first destination and bought a roaming bundle via the app. Was billed for it but it never worked. I loaded Airtime to make a call and the data used all my airtime. I'm now down R800+ and still unable to use my data whilst travelling. I have to look for wifi hotspots. Try using the call centre Whatsapp and OMG they can't help. Emails don't get answered. I'm on one of the most expensive contract packages with Vodacom, my bill is close to R3k a month but I can't even use my phone when travelling. What's the point of having these business contracts!!!!!
