EWallet issue still ongoing for 3 months

Once again I have to take to social media and HelloPeter to call FNB to action. I have a small issue but for me it is something I would like resolved. My EWallet has not been working since I changed my phone number - logged a call and received a reference number - Rh ********** 3421 from then over 2 weeks ago . Someone called me to say that the old number was never deactivated however he had activated my new number but someone was going to email me instruction. Well Ms Nathalia Lazarus did email me on the 12th July giving me instructions. When I followed her instructions to the tee - i recevied an error message (see attachment) I immediately emailed her back and again and again and again but no response from her - I assume that FNB dont know how to fix the problem so they are keeping quiet. I am so irritated because FNB profess to be the "Best bank" Youre the worst bank and you are getting arrogant .......
