Sony Xperia upgrade

Upgraded my cellphone contract end of April. Vodacom at first did not have the phone I upgraded to in stock so I had to wait. This happened for the 3rd time in a row with my upgrades. I upgraded to a Sony Xperia with a certain accessory that was included in the contract, which after 2 months I have not yet received nor have I had any feedback on my query. This is unbelievable. I am so dissatisfied with vodacom that I decided to switch to another provider.
