Dear Customer Assitance,

I'm a customer of your online shop, my name is XXX. Recently, I made an order 3528963XXX with price of $199.97. Unfortunately, I notice that your online shop is promoting a new activity with more 20% discount. However, the purchase price has down but my order still on the way. And it is hard to accepted to me.

I think, therefore, that your may able to assit me on this order. Would you please help me to make a refund for this price difference $XX.X  to my original method of payment？

Waiting for your feedback.
Sincerely,
XXX
