Still waiting for my Galaxy S6 Edge

I wanted to convert my existing Vodacom prepaid sim to a contract for the Galaxy S6 Edge. After being transferred to various departments and getting conflicting advice, I finally pre ordered the device on 25th March. I received the sms saying I'll be contacted to confirm my order - that never happened. I called on Wednesday and was told there's no way to check that my order was successful, I'd have to wait until Friday. This morning I called and was told that when I ordered, I hadn't selected a package. The website won't allow you to continue without selecting a package! The person I spoke to said she would call me back... I'M STILL WAITING. I was told there aren't any gold devices and she was to tell me when they'd be in stock. I have emails, reference numbers, names and an sms to prove how hard I've been trying to RECEIVE AND PAY FOR THIS PHONE. It's pathetic how poor Vodacom's customer service is. I expect a favourable response to this complaint along with a reasonable compensation. (Reasonable by my standards)
