Made a deposit for burial plots, but haven't signed a contract due to red flags re:their integrity. Can I reject the contract & get my deposit back?

My mom, siblings & I were purchasing family burial plots & I'm the main contact person, although my mom did the original legwork. The original salesperson that contacted me for the deposit was rude & high pressure, insisting on a deposit before I had even seen terms of the contract. After she did finally send a copy of the contract, I spoke to the director instead & placed a good faith deposit & by email noted corrections (in the body of the email & in a scanned image of corrections) to be made to the contract, after incorporation I would then review & sign. It took 6 days (4 business days) for the contract to be returned but additional errors were introduced despite clear instructions and text provided. We question the integrity of the salesperson and the business. As I have not signed the contract, would like to cancel the entire transaction. Can I expect return of my deposit or do I need to litigate?
