Continental Airlines 3 months - still no refund! of ONBLY $6.00 Box 4607. Houston, Texas 77210-4607

This company is the poorest that i have EVER send in consumer relations and customer service!  It's almost 3 months since my flifght It's almost 3 months  when I paid $6.00 FOR 2 HEADSETS- PAID CASH- ONLY TO FIND THE TV  DIDN'T WORK! THE STEWARDESS COULDN'T RETURN MY CASH AND SIMPLY STATED "JUST CONTACT CUSTOMER" CARE" AND I'LL GET A QUICK
REFUND"!!!
 now i've called ( at least 10 X) and been placed on hold for close to an hour each time. I've sent emails, completed FORMS- YOU NAME IT  AND   still UNRESOLVED!!  The reps even  THE NERVE TO CALL ME 4 TIMES IN 1 DAY , AND DIDN'T EVEN LEAVE A NUMBER TO CALL BACK! FINALLY, WHEN I DID ,AGAIN- ON HOLD FOR 50 MINUTES! ONLY BE TOLD THEY'LL RECORD THE INFO IN MY FILE! YOU'VE GOT TO BE KIDDING! 
$6.00!!! MY REFERENCE # IS 4781679. WHAT A DISSERVICE They  ARE!
 
It's only  $6.00! it's not the money it's the principle; they had no problem charging me, but couldn't return the cash within 5 minutes!! and made this process frustrating and humiliating! The nerve to place customers on hold over 45 minutes just to be given this treatment and run around!
