Unacceptable pathetic service

FNB, your online banking service is unacceptably inconsistent. Downloads either do not work, only work at times and download in different formats. ALL from/on the same computer. I raised this once before at branch level but no reaction. OTP SMS's ALWAYS SLOW. Not only do I not understand this and the fact that it cannot be corrected, I also have to update preferences on EACH AND EVERY LOG IN. I do not want promotional material, NEVER EVER. I've had 4 accounts and an eBucks account with you for 20+ years and would prefer to keep banking with you, but over the past two years you're surely making this difficult. Simply put, just catch a wakeup. This is unacceptable from a bank that previously was known to have rendered good service.
