Unprofessional poor service

I lodged a complaint last week about my password being blocked , I then received an email yesterday requesting for my ID copy which I sent today, I was given a number to call *** after submitting, I called today and I was put from pillar to post and an agent from digital department said there was no escalation only my complaint and he said I should get an OTP from an ATM, the service is poor and they reverted to a number that I no longer used after blocking my password, I want my contact number to be updated with immediate effect as I have no time to go to the bank and not willing to because I am not responsible for this problem, I can’t access my bank account and this is irritating and costing me time to have to report the same issue everyday, unprofessional service and no sense of urgency by FNB staff, I want this matter resolved before close of business
