Vodacom online shop - service PLEASE

One week later, i am sill awaiting someone's assistance in changing the color of a Phone I purchased. To avoid the unnecessary delivery of the wrong color, I've tried non stop to get through to someone to assist. Customer Care refers you back to online , and vice versa. I had a gentlemen call to try and assist, but nothing further. I viewed RAM's website, and it showed the phone was sent back to Vodacom. Now you have my Money, and nobody even bothers calling to follow up. I would just like the phone i ordered in a different color. Your website isn't user friendly, but most of all, no care what so ever to even follow up on a customer ???? One week later, can I beg any more for someone to assist ??? Order #***
