Frustrated RMB Private Wealth Banker

On Tuesday morning the 12th of September I tried to access my rmb banking app on my phone and I logged in but could not transact as all tabs were blank, I then contacted the rmb call centre the lady advised that I reboot my app, explained further that I should delete the app on my phone and re-install ,, I then proceeded to do so, thereafter all seemed well, until I arrived at work, then a transaction appeared on my screen, prompting me to accept or decline a transaction for R48 500 from a Samsung phone , which was foreign to me so I immediately declined, but the transaction somehow managed to go through even after I declined,, which is extremely odd , I reported this immediately to RMB forensics on the phone, then later on decided to drive to the Brooklyn branch where I was advised my account would have to be blocked for 24 hours, the R48 500 was still reflecting as available in my account at the time my accounts were blocked, today the 18th of September I went back to the branch as I was not receiving updates from the bank regarding my case and I still did not have access to my accounts, It was then that I discovered that the R48 500 had now disappeared from my account almost a week after my account was supposedly blocked!!! I am not given an explanation as to how the funds came out of the account when it was blocked! I am being sent from pillar to post , as a medical doctor running a practice with ill patients in the waiting area that I need to attend to… now I must be chasing the bank .. spend a minimum of two hours while the bank staff is on the phone with FNB ***** department …this is extremely frustrating and affecting my business negatively !!
