Very poor customer service, need help

I'm writing this on behalf of a friend. She has a Gateway Tablet TA6 and has had numerous problems. She has sent her laptop back for repair a total of 6 times now. The laptop is still under warranty until January. This latest round started over a month ago. The screen was not holding itself up anymore so she sent it back for repair (her expense for shipping). She got it back and the power lights were not coming on and some were blinking uncontrollably. She had to send it back again (shipping again at her expense). It took 2 weeks to get it back the third time and when she did get it back the power adapter no longer charges the laptop. It looks (to my eye) that they replaced the internal power components and now the previous power adapter does not work.

She called and they told her she needs to send the old one back (again at her expense) to get a new one or they can charge her credit card and send her the new one (3-5 business days) and refund her when they receive the old one.

We called to get the power supply sent overnight since she is a college student and now will be without her laptop for a total of 3 weeks. My question is, is there another number we can call to get a US based supervisor. They will not ship the power adapter without charging her CC which is ludicrous since this issue is their fault.
