Simply process of updating details taking for ever with no feedback given

The most unpleasant experience ever. Service at this institution is of the lowest quality.

Have been trying to get my contact details updated (because I no longer have access to these details) to be able to access my Banking app, for over a week now.

I have made over 60 phone calls over the last week. Every day I get promised that it would be resolved by the end of the day and that the agent will phone me by close off business that day. No call back received what so ever over the last week. These false promises was even made to me by a Manager.

I am extremely disappointed, and so fed up with the constant struggle and no feedback, that I received. I have even emailed the complaints email address on numerous occasions the past week where promises of complaints being taken serious are made and that feedback will also be giving, well NO feedback received up to date.

For a bank that promisses so much your service delivery and feedback is absolutely terrible.

Really considering closing down everything and taking my business elsewhere, where I as a client would be respected and treated like my issues do matter.

If it would be possible to give a 0/5 stars I would, as this is what I rate the service of this bank.
