GIVING PRIVATE INFORMATION TO 3RD PARTY

I HAVE ENQUIRED ABOUT A LOAN @ CAPFIN , SO THEY SEND AN SMS IF THEY CAN ACESS MY DETAILS VIA MY BANK WHICH I AGREED VIA SMS , SO EVERYTIME I'M CALLED BY DIFFERENT CONSULTANT I TELL THEM THEY MUST TRY TO CALL ME @ 10H30 OR 17H00 AND THEY HAVEN'T BECAUSE WE ARE NOT ALLOWED CALLS , TO MY SURPRISE MY AUNT TOLD ME THAT THEY ARE BUSY CALLING HER REGARDING MY APPLICATION TO WHICH I DETEST STRONGLY BECAUSE I BELIEVE THIS IS VERY WRONG AND IT'S A PRIVATE MATTER
