Hi Nicole, welcome to the forum!!! It's good to have you here, though the situation that brought you is unfortunate...
I would def say try to have the engine rebuilt by a reputable person/shop, also have them go over everything as your car may have things wrong with it that are NOT apparent to the standard Mazda Tech (sadly most Mazda dealerships don't know fuck-all about rotaries). How many miles is on the car?
Where about in the country are you? Sometimes it is ABSOLUTELY worth it to drive (or tow) hundred(s) of miles for a good rotary shop.
Hopefully we can help you get your car situation figured out, and you're welcome to stick around for the punch and pie afterwards
Cheers,
Levi
