Welcome to Justanswer.com, my name is Dustin.
I'm sorry to hear about the issue you are having, I will do my best to help you resolve it.

My apologies for the delay in getting back to you. By the time you had responded 30 hours later, I was off shift.

As far as charging you, I have absolutely no control over when or what you are charged. When you signed up it mentioned clearly that a 5$ deposit would be placed, and the rest would be charged when someone replied to you.

As far as repairing the device, lets try this first

Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R.
Turn on your Mac.
Press and hold the Command-Option-P-R keys immediately after you hear the startup sound.
Hold these keys until the computer restarts and you hear the startup sound for a second time.
Release the keys.

Next, hold down the left shift button when you start your mac. This should start the mac in safe mode.

Now, try and open your airport utility, can you see any wireless networks now?

Is the card showing in system preferences, network?

Please respond when you can and let me know the outcome of the steps above, and we will either continue if needed or marks this issue as resolved if its fixed.
