Irritating experience with FNB app chat feature

I tried the chat to an agent feature on the FNB app to find out about an unauthorised debit that went through my cheque account but the "AI" feature insists on offering me standard options and then read "debit" in my question as debit order. I'm now endlessly dealing with a debit order desk agent called "Nisha" who keeps asking me the same unrelated questions. It's absolutely hopeless. How do I get my query sorted?
