I GOT THE WRONG ROUTER

If i get a call from the guy that does twitter complains 1 more time il knw how usless vodacom is he is not usefull at all. I took out a contract on the 28th of last month i bought a Huawei R218h router with 20gb and this is the response i got 'As discussed we have confirmed that the Vodafone branded devices are not manufactured by us. The router in question is equivalent to the Huawei and carries the same warranty. An offer to cancel the contract has been made and we have confirmed that we are not able to exchange the router at a later stage' then suggets i should cancel my contract i dnt want to cancel but nowhere did vodacom mention id be receiving a vodafone router instate of the Huawei router i initially ORDERED i swear am sick n tired of explaining the samething over and over and OVER... I GOT SOMETHING I DID NOT ORDER and thre is no were in the contract were it mentioned rebranding or me getting a vodafone router do you guys even understand were i am coming fron as a customer???? I am super annoyed i swear
