Shocking service RMB Private Bank!!!

Actually complaint for RMB private bank. I'm ANGRY at the incovenience & utter waste OF MY time trying to communicate with my private banker& his team; INCREDULOUS that I'm dealing with issues like this at a private bank; FRUSTRATED with invalid, illogical and VARIABLE reasons given by my private banker to appease me and still no resolution since 4 March 2025 - 2.75 months My ISSUE -: I can't get a MARCH 2025 STATEMENT from the app or from my private banker & his team. What bank cannot produce a March statement?!! I ALSO routinely have a statement issued as at 6 of month eg 6 February and get given an EXACT amount due & payable at 30 Feb, which automatically gets paid monthly VIA an internal debit order - been so for 21 years. HOWEVER an ANOMALY also occurred with FEBRUARY 2025 statement - it was processed 26 Feb and date payable was the 28 Feb (2 days!). The amount payable was DOUBLE what I pay monthly - so on 4 March a double amount was paid from one account to my credit credit card. This affected all subsequent debit orders that were scheduled to go off after 4 March as I was overdrawn. Infuriating!! THEN on 30 March I had another near DOUBLE amount go off my account - so in essence reckon I've paid in advance. I've looked at my transactions & even those appearing after the closing date of my credit card have been included and payable in the same month (what happened to 30 days plus advantage?!) BY THE WAY this happened last year March 2024 too - a double payment of a SIMILAR AMOUNT ( only few hundred rand difference). IS THIS NOT SUSPICIOUS OR IS IT JUST A COINCIDENCE???! It took 3.5 months to try resolve with another private banker& his team with all same problems I've had with current team, arising. I gather wasn't resolved! Various reasons to name a few given: -this problem has only been raised by you; - it's a double payment in same cycle which is your fault; - can't produce March statement at all & all customers were forwarned;- my other account Ts and Cs are making my credit card payments unaffordable - my other non related account is up for renewal &I must renegotiate T & Cs Etc I have asked for a recon - Instead I got given the other account statements for me to work out. I've asked for a meeting when issue arose and no dates I've suggested have been considered yet. Friends are also concerned about suspicious activity & suggested I contact ***** department. I DO NOT WANT TO DEAL WITH MY BANKER OR CREDIT ADVISOR. I ONLY WANT A VERY SENIOR MEMBER NOW TO DEAL WITH THIS!!!
