Trade-In?

 

But when I bought Mouse and Keyboard from Dell.com, all transactions were declined.

Although my order did not go through, $127.19 was taken by Dell. ($127.19 is the price for mouse.)

Currently the balance of credit is only $74.81.

Do you happen to know below?

1. Why declined?
2. Why was my money taken($127.19)
3. Do you know any e-mail or direct phone number of Trade-in department of Dell?

FYI, customer service was worst. It did not know anything on my issue. It has tossed my issue only to another person or departments. I spent almost 3hours but cannot solve the issue.
