SLING TV N/A NO MONEY BACK FOR CANCELED UNUSED SERVICED Maryland

I SIGNED UP FOR SLING TV SERVICE LURED BY THEIR SEVEN DAY FREE TRIAL OFFER

AND THEIR COMECIAL THAT SAYS "TV ON YOUR TERMS NO LONG TERM CONTRACT NO HIDDEN FEES CANCEL ANY TIME"

I ALSO WAS LURED TO PAY TWO MONTHS IN ADVANCE BY OFFERING ME  A FREE ROKU EXPRESS DIVICE

BUT BEFORE I ACCEPTEDED THERE WAS A NOTE ON THE SCREEN REASSURING ME THAT I WILL USE THE SEVEN DAY FREE TRIAL BEFORE THEY CHARGE ME FOR THE SERVICE I SIGNED UP FOR

A DAY AFTER I SIGNED UP I DECIDED I DIN'T LIKE THEIR SERVICE SO I CANCELED SO I ONLY USE ONE DAY OUT OF THE SEVEN FREE DAYS THEY OFFER

OBVIUSLY I WAS TRYING TO AVOID THE PARTIAL SERCICE FEE THAT THEY MENTION ON THEIR POLICY 

AND THE ON LINE ACCOUNT SHOWS NO MONEY WAS COLLECTED FROM MY CREDIT CARD AT THAT TIME OF CANCELLATION

SIXTEEN DAYS LATER I GOT MY CREDIT CARD STATEMENT SHOWING THAT THEY DID CHARGED ME ANY WAY FOR THOSE TWO MONTH OF SERVICE I NEVER USED BECAUSE I CANCELED  WHEN I WAS STILL ON THE SEVEN DAY TRIAL

IN FACT I USE ONLY  ONE OUT OF THOSE SEVEN DAY  TRIAL THEY OFFER

I CALL THEM AND ASKED WHY THE CHARGED ME IF I CANCELED  WHILE I WAS ON THE FREE TRIAL 

 THEIR ANSWER IS THAT THER IS NO MONEY BACK ONCE THEY GOT PAID AND MY ONLY OPTION IS TO USE THE SERVICE

I FEEL LIKE I HAVE BEEN ROBBED

LOOK LIKE IN THIS COMPANY THERE IS NO COSTUMERS SATISFACTION COMMITMENT

HAS THIS HAPPENED TO ANYBODY ELSE?
