As for Vodafone not being able to help...? I worked for a telco in the past, and it's not about being unABLE to help, they just don't want to or don't know how. If I were a 75 year old lady and went into a Vodafone/Spark/2 Deg store and explained my specific situation, I'd expect someone might try to help. They can't, so I came here. But thanks anyway. Next time I'll just call a help desk in India. :D
I'm not sure why Vodafone should be prepared to offer help for the use of a product outside the scope of a supported scenario. They've very clearly told you that the device needs to use a software dialer, and that's something will support. I'm quite sure what support you are expecting Vodafone to actually offer - there is absolutely nothing they can do to make their product work with a D-link router
D-link should be your support channel for their product, and I would fully expect them to provide support with their product if you had a stick that was supported. As you've got a USB stick that's not supported by then, there isn't much they can really do.
