Squarespace is service provider that makes it easy to build websites that look good. I would reach out to them via their website as only Squarespace would be able to answer you question properly and they will need information you probably don't want public to figure out what happened. If you really never provided your billing information then it is possible you are a victim of identity theft.
I don't understand your question. Was there a transaction that took place? Need more info Jimmy
