How bad can it get?!!!

After applying for a contract we waited 2 weeks for stock. We then received a broken unit and returned it the next day. We are now still waiting for a new unit and to top it all vodacom Supp**** a wrong pin for the wifi router that came with this package. We were informed that almost 2 GB is used up by trying to login with this wrong pin. I can't see how that is possible. Never the less! To top it all, we have just been charged for the contract that we have not yet had the chance to use. We incurred expenses because of Vodacom and their don't care attitude and now we are paying for absolutely nothing! How can this be legal.
