Delivery of incorrect phone colour

Cellc upgrade department spoke to me over the phone and told me that i qualify for a phone upgrade. <br> <br> For which they told me that it will be delivered to me. After specifying that I want Silver. <br> <br> Color is one of the most visually distinctive and personal things about a new iPhone, which makes it one of the most important choices you'll have to make.<br> <br> Today I get delivered a space grey iPhone 6s after repeatedly asking and confirming with the agent that i need a silver color. upon contacting the customer care they mentioned that they only have space grey.<br> <br> Why is it so hard for Cellc to follow instructions??? Seriously! The most pathetic cellphone network ever! Don't know why I even bothered opening a contract with you!
