Toshiba Toshiba International, Toshiba Computer, Toshiba America Sold us a lemon computer, failed to repair it the junk, and lied to us Irvine Nationwide

After buying a Toshiba laptop our computer's keyboard stoppe working.  We returned the computer for repair and the computer are back with a functioning keyboard.  However soon after that the EXACT problem happened again.  Toshiba had us return the computer to be fixed.  Again shortly after return the EXACT problem occurred yet again.  Toshiba continued to have us send in the laptop only to have it temporarily repaired and never fixed.  Finally, after 4 times of doing this they provided us with a replacement laptop.  The replacement laptop arrived and the speakers do not work.  We have since asked for a refund, but Toshiba is unwilling to give us a full cost replacement, even though our computer broke for the first time less than 30 days after we bought it.
