ONECALL MD SCAMED ME BY INTERNET

I WAS OFFERED A CREDIT GIFT CARD FOR 2.95 TO SIGN UP FOR THIS SERVICE. I TOLD THEM I DIDN'T WANT THE SERVICEO NECALLMD TO CANCEL AND THEY HUNG UP ON ME. THEN THEY CHARGED MY ACCT 2.95 THEN CHARGED ME 4.95 AND TOLD ME I HAD TO CALL WITHIN 10 DAYS TO CHANGE. I TRIED CALLING THEN I CALLED THE 800 NUMBER AND THEY CANCELLED IT NT REFUSED SO I WOULD NOT BE CHARGED 34.95 BUT WOULD NOT REFUND THE 495. THE CHARGES CAME FROM 2 DIFFERENT COMPANIES I BELIEVE .. I KNOW I WAS STUPID TO FALL FOR IT BUT IT IS A SCAM I'M WORRIED THAT THEY MAY TRY TO CHARGE ME IN THE FUTURE. Iwas offered a gift card doe 100,00 for 2.95. tosign up for this service I told them I didn't want the service. scam.
