You do not provide email contact on internet banking

I do not have a telephone so cannot, and anyway would not, make my complaint via telephone. I cannot see on your Internet Banking website how to contact you via email, therefore I am resorting to stating my complaint via this website. You are now charging me 80c per SMS notification when policy on your website states that the cost is 40c. Please advise why you are charging me double fees. This is what is on your website: "This service helps you keep track of money in or money out of all your savings accounts by sending you updates to your cellphone. You can also request the balance of your Daily Savings Account by sending the word BAL via SMS to 31646. Updates are charged at 40c per SMS."
