Poor service

My cell phone was ******, which forced me to do a sim swap. After the sim swap, I have not been able to do any internet banking, as I don't receive the secure code on my cell phone. After spending many hours on many days at the branch, they have not managed to fix this. It is also a critical time, as it is month end. It is absolutely useless! A few months ago they allowed payments to go off my credit card that did not authorise, and now they are so secure that they can't even allow me to do my banking! I am sure there must be many people in the same position. If I wasn't in the process of immigrating, I would have changed my bank.
