Who most likely is the woman?

M: Customer service, this is Rick speaking. What can I do for you today?
W: Hi, Rick. This is Becky Matthews. I bought a television at your shop last week. Today, my credit card statement came, and I saw that I had been charged twice for the same purchase. | would like to have the extra charge removed from my bill.
M: I apologize for the error. We’ve been having some trouble with our computer system. You’re actually the third person to call with the same issue. We’ll be happy to refund your money. If you give me your receipt number, we can get the process started right away.
