Missing router and shocking after sales service

Calls go unanswered, messages are ignored! I ordered a router that was meant to be delivered last week. Since then I have received no communication from you or from the couriers with regards to where the router is. Vumatel arrived at my residence last week to fix the connection in preparation of the router and I still have heard no word about when to expect delivery of my router. I'm supposed to be billed at month end for an Internet connection I haven't even made use of because NO ONE can tell me where my router is!
