Update Credit information As you are supposed to Monthly

Good Day RCS it has now been two months since you last updated my Pick n Pay Store Card information at the National Credit Bureaus.Are you by law not supposed to send Account Information every 30-45 days Or does this not apply to RCS.All my Other accounts updates atleast once a month on TransUnion and Experian but not RCS Pick n Pay Store Card. Is RCS exempt from this rule or law?...I Phoned both Pick n Pay and RCS to update Account information on The credit bureau and None of your consultants understood what I was talking about.
