Liar is a name for someone who habitually tells things that are not true. Is that what you do ?
A one off is a lie, something which may make folk suspect the teller is a liar though.
I do not believe for a moment if you give someone true information and they mislead themselves that the true information is suddenly defined as lies. That is a nonsense.
Taking your version of events at face value, you do not claim to have lied, so I don't see that you qualify.
However you must've given the impression that you wanted whatever it was, so you should be more careful in future: and in future accept whatever is given to you with thanks, as it wasn't necessary to inform the giver that you didn't appreciate their efforts and therefore make them feel bad. If that is what you did, then maybe an apology is in order.
