Directv Directv&Att Took money from my account for my sister-in-laws bill and said my debit card was the primary v=card on file even when she told them it was not so now I am out 349.79 dollars due to thier stupidity. Nationwide

 Actually this entire situation IS your sisters doing. SHE agreed that ANY remaining amount left on her account would be taken from whichever card is on file. By on file, they mean whichever card is CURRENT and HAS BEEN USED to pay a DTV bill. This was ALL spelled out for your sister when SHE READ AND SIGNED her opening paperwork. While its understandable IF she forgot, but odds are that SHE didnt read what she was agreeing to and YOU are the one who gets to eat the costs SHE incured. DTV has NOT activly ripped YOU off. THEY were ONLY doing EXACTLY what they told your sister they would do if there was a balance remaining.

So you paid your sister in-law's bill.  Simple fix...she just reimburses you...provided she is a respectable person!
