FNB CRS department seems inefficient

On 8 April I get an email from *** requesting tax information otherwise my account will be frozen. I rep**** the same day with the required info. On 12 April I get the same email again. I respond again. Contact FNB via online chat asking if there is anyone monitoring the email. Khanyi eventually puts me through telephonically to the CRS department. Nobody answers and the phone goes through to the prompt for rating 1 to 5. Obviously a 1. Come on FNB, is this the way you treat your customers, especially those of long standing? Get your act together please and kindly acknowledge receipt of Self Certification document!!
