Email support VA

I need you to be able to answer customer support emails.

Some examples are:
-Where is my product? I've been waiting for over a week and I will not tolerate this
-Please help me change my item from white to blue
-Reply to me with a numerical zero if you're reading this
-I'm unable to make a payment. You lost a sale because I'm unable to use my card.

Assume my name is Elizabeth and I ordered a $15.95 white shirt at 1st October with free shipping.
Answer me with your proposed answer with the above data.
