求预约电话卡， 万分感谢！

I want to make appoint for my mom on 2/22 or 2/23. I bought a appointment card. I called twice and there is only 5 minutes left. So I ask for appointment card that has one or two minutes left. I am afraid if I call again, if not the date I want, I will not have enough time to finish the appoitment. My email is mengd7@yahoo.com. Thank you.
