DISCOVERY BANK - UNRELIABLE SERVICE

I recently joined Discovery Bank as part of their transfer of their previous credit cards from FNB. I had a primary and secondary card for my wife. With the transfer my wife's number is now listed as my primary contact on the bank app and my number listed on my wife's app as primary. I have now contacted Discovery on numerous occasions to swop our numbers from secondary to primary on both my and my wife's app. On all occasions the service advisor had to enquire with the line manager to assist. I was advised on all occasions that the problem will be escalated and resolved and that I'll be contacted to be advised if the issue is resolved. After more than a month's attempts this has still not been resolved. Everytime I need to make an online payment I have to contact my wife or vice versa to get the OTP, as my primary number is listed as my wife's number. Case number 457128 Discovery. Maybe Discovery will address this issue now that I've gone public. I am extremely disappointed with the support I have received from Discovery Bank. I am a client that subscribes to the full suite of financial services with Discovery, i.e. Medical Insurance, short term insurance, life cover, Vitality, banking. At this stage I am seriously concidering moving away my whole portfolio from Discovery.
