Unhappy customer

I am very unimpressed with the level of service received from Vodacom. As i was hoping to join the Vodacom world for the first time as a first time contract applicant but after the service i am getting with them i am really not impressed. I app**** for the Apple Iphone 5s device and they told me they currently don't have stock and they will put my order on the back log and they could not give me a date when i should expect the phone. It has been 3 weeks now since the application and still no stock. I went to one Vodacom shops and they have stock and the consultant advised me to do a dealer swap for me to get the device from them directly, i called Vodacom online and they telling me they cannot do a dealer swap, i asked to rather cancel the application so that i can go do a new application directly from the store. A week later one of the agents advises that the application cannot be cancelled because its been put on back log and awaiting stock, but my problem is they cannot give me a date when to expect the phone. I find this very frustrating and unacceptable as i could wait for the device for months to come meanwhile there is a store which has stock available currently.
