FNB Not very customer centric

Hi

Got this sms which I don't think is very customer centric in what I assume is the Business Banking segment (I have about 8 FNB accounts). I tried calling the number below but waited 10 minutes before I hung up. On the second call I spent 30 minutes speaking to Tiffany Williams who said she would email me the necessary info. Still waiting. Very poor way of dealing with customers by sending an sms like this that could be phishing? No email or call was made to me prior to this to explain anything.

"FNB:-) Your account will be frozen in 2 days if your tax information for SARS Common Reporting Standards is not provided. For more information contact us on ********** 709. FNB, a div of FRB Ltd."

Please help.

I have sms'd the FNB CEO Jacques Celliers but no response yet.
