Vodacom Contract Wrong device received and Unable to change.

2 Problems, 1. I signed up for the 10Mbps uncapped service which advertised the Alcatel router, I received a Nokia router instead. The Alcatel uses much less power than the Nokia router. 2. I decided to rather change to a higher contract plan, upon consulting the shop the said it is not possible, but the official terms and conditions says it is possible, especially withing the next 5/7 days after signup:

Migrations You can migrate to another price plan option however the new plan's data allocation and terms and conditions will be applicable. Vodacom migration rules will apply. You can migrate into the Home Internet Capped price plans from another Home Internet price plan however the new plan's data allocation and terms and conditions will be applicable. If you migrate to a lower price plan you will be liable for a downward migration fee. Migrations on Top Up plans will be pended until the end of the month and the new price plan will only take effect at the beginning of the next consecutive calendar month. If you migrate to another price plan, your contract period for the Service will remain unchanged.
