Worst bank ever

I opened a savings account and when i did so the consultant advised that I could download and register on the app myself. I am now overseas and cant register for the app as I need to go into a branch. When I log a request for assistance they pass the buck and gave me a call centre. When I call the call centre the advise that i failed the questions when i clearly answered them incorrectly. They probably loaded my information wrong. I am sitting abroad with no access to my funds. I am awaiting a deposit but nobody will give me a balance. I cant even draw money. I booked a hotel room with my card number only to find when i arrived overseas that the hotel was advised that the card number was incorrect which it was not on the hotels system and my room was cancelled.
