Huge Disappointment!!!

They refuse to listen to their customers. I send an email every month to their accounts team and still they are charging me with interest when I specifically opened an interest free account. Even after the switch to RCS i told them my account and all my purchases are to be interest free yet I am still having interest charged on my account monthly. Your cashiers don't even ask for the type of purchase but we are surprised by interest charges at the end of the month. This is unacceptable.
