BNZ home loan partner left suddenly and I am a bit upset of this behavior

Hello,

I just finalized my home contract and wanted to email bnz loan partner to start the process from Monday. I already had contact with her. Suddenly I got an email that she is on leave for 5 weeks and gave another email of another person. I don't like this behavior and I want to go with mortgage advisor to see which banks suit or even directly go with the bank directly. Is that Ok? Legally and morally?

Can I stop continuing the process with her? We sent our documents to her but did not sign any agreement or anything else though we have had several emails.

What is your suggestion?
