A legal question, not an ethical question - what's your take?

Details:

Someone (who I have never heard of) gave MY call phone number to a whole bunch of car-hauling companies – this guy wants his car hauled from Michigan to Arizona, presumably for the winter.

I am getting text messages, some with pricing and ‘contract terms’, from these car hauling companies. And I have gotten 5 phone calls on my cell phone from various different haulers.

Here’s my question. Suppose I text messaged back to one of these companies – “Yes, it’s a deal” as if I were the guy who caused this mess by giving out the wrong phone number in the first place.

I know the ethics – it’s a shitty thing to do,

But what’s the legal side of it? I am not the guy, I don’t need a car transported, I have no relationship to the companies in question, and it’s doubtful they would ever find me.

If I said “yes, it’s a deal”, am I on the hook for the service?

I would do this more because they have annoyed me five times this morning.
