FNB cant change OTP contact details, *********** staff?

FNB cant change OTP contact details for the past 10 years. Every year I call, log, app, message etc. fnb consultants to change my otp details. They cant give ref numbers for change requests. Nothing happens after every query. Very very dissaponted. Is it fnb’s process that ling term clients are not assisted or should go into a branch in these days..is there a better bank out there?
