Change of ownership and upgrade of a business cont

I have been trying since jan 2015, via email as well as physically handing all documentation to the vodacare in Somerset mall, to change the ownership of my cell contract. Vodacom politely changed the banking details the debit order is taken from, in the name of the new company, but cannot manage to change the ownership. I find out that i have been due for an upgrade in may 2015 and that i am paying almost double for a contract that gives me almost half the benefits of the red business i am qualified to upgrade to. I saw a special offer for a upgrade including a galaxy note4 that expires on 10 August. Trying to upgrade from the Vodacom store in somerset mall i was told that they can no longer get hold of the phones. Speaking to business call centre i am told that business call centre will only get the deals after they expire at the stores and that i have to wait. I phone back today and get told that contract can be upgraded but i cannot have a phone with it as they haven't gotten the new deals but i must go check out the store as they can upgrade me. I have a business contract but receive worse service than on my personal that has a spend of R300 a month
