Poor Service from FNB Private Wealth

I am a Private Wealth Client. I made a request to my Private Banker Lindelwa Matiwane via email on 15 March22 at 16h46. I followed up with WhatsApp messages on 1 Apr, 08 April, 23 April, 25th April (no response), 26th April (no response), and 29th April (no response). Due to her lethargy, I missed Level 5 eBucks status for past 2 months. This has had financial implications for me.
