Justified Interrogation???

So I was speaking with a vendor about catering and they told me to send my venue name. I sent them the name and address. Then they asked for my phone number because they said they don’t send info without the proper research due to other caterers harassing them to the point where they started a federal investigation. So weird. But I sympathized with them and gave them my phone number. I had to call and email them to get any info. So they write again and said my venue is not on Instagram or google and could I send more info. I told them the venue is newer. I sent the address again and the owners number. So they send the proposal... BUT then send me another message an hour later asking why I was saying “my husband” if im getting married? I was at work so they sent another message asking if I had “any questions or answers”. Then blocked me because I could not respond readily. I married very young at a courthouse and now that we bought a house I am having a formal wedding. My father in law just purchased an old cinema that he transformed into an event hall. I gave them a poor review which they are now disputing. Am I overreacting or was their questioning unsettling? I am still trying to book more vendors but would like to know if I should expect this level of questioning from others.
