MISLEAD INTO SIGNING A CONTRACT

I CAME ACROSS A BODY LAB CONSULTANT AT TRAMSHED SHOPPING CENTRE (PRETORIA) FEW MONTHS AGO. HE CONVINCED ME TO SIGN THE GYM CONTRACT FOR 2, I TOLD HIM I WAS A STUDENT AND WAS NOT WORKING. I ALSO TOLD HIM I WILL SPEAK TO MY SISTER FIRST AS SHE IS THE ONE PAYING FOR MY COLLEGE. THE CONSULTANT TOLD ME THAT I MUST SIGN THE CONTRACT , THEN TALK TO MY SISTER AND HE WILL CALL ME BACK TO CONFIRM. TO MY SURPRISE, I STARTED GETTING LETTERS, SMS FROM BENNETT &amp
