Fingerprint technical issues blocked access to my savings

Won't mention a branch yet but had issues accessing my savings due to fingerprint verification and that was it, left since was moved back to the queue to make a call to African bank support who asked if they followed the procedure and couldn't confirm since I was moved back to the queue while help desk was attending another customer. This means I had to stay and buy another airtime and try online verification again, Will try again on another branch when I have capacity
