Conny seeking damages for breach of contract

Hello!

I've recently received a threatening email from Conny that they will seek to charge me ~7k in damages if I don't proceed with the documentation for the rent agreement reduction they have been asking.

The thing is I've never actually signed any contract with them, I pretty much just used their website to "check my savings potential", which triggered them to start emailing and calling me asking to sign a power of attorney and send other documents to proceed with it. I've never answered their phone calls nor their emails. I don't see how could there be any biding contract between me and them for simply getting a quote on their website a couple of times.

Has anyone gone through a similar situation with this company? Do they really have any legal basis here to say that we have a contract and I'm in breach of it or is it just some scare tactics to make me actually use their service?
