Online application

I app**** for a loan using the app. Was happy that that process was fast and easy. Signed the agreement and received the confirmation that everything was in order and the money would be transferred. A week went by and the money was not transferred. Called the bank for assistance and they said they’d escalate the matter to the relevant people to assist me and should expect a call in 24hours. More than 24hours later there’s no call. Call again and I’m told the same thing. Explain that I still haven’t been called and they say I will be called in 24hours. No call once again. I call again and I’m told that the application is now expired and I have to redo the process. I redo it but now I’m charged a higher interest rate and the fault wasn’t even on my side that this had to be redone.
