That bitch is stupid. All she had to do is to call her credit card company to dispute the charge. The cc company will then withhold the fund to Google, Google will then issue a charge back to the seller. Transaction complete.
She was complaining to the wrong people. If you went to a restaurant and the waiter charged extra tips to your card, would you call you company that processed the card transaction? NO! You call the restaurant and if they don't fix it, you then call your card company. Dumb bitch.
