Can a seller legally avoid closing on a deal?

[Sergio P Ramos]

I recently went under contract on a property through my wholesaler. On closing day, the original seller (not the wholesaler) decided they did not like the terms agreed upon. At this point, the earnest money has been collected, and we were under contract to close on that day.. the original seller then tries to resell the property through another wholesaler that i happen to know personally. I was sent the same house I was already under contract through a different wholesaler. The wholesaler that I went under contract with has taken legal action against the original seller. Has this ever happened to anyone? Do I have any legal rights to this property since I was already under contract and was due to close? Would anyone have any advice for this situation? What options do I have under this situation besides ait and wait?.
