Refusing to sign cancellation?!

[Seth S.]

Hey guys! 

Looking for some advice on a weird situation I am in. 

We made an offer on a SF home and had until the 24th of Jan for due diligence. Hired an inspector; got results; took out big findings and sent them to the agents with a request for 10k credits. The sellers countered with 2k to which we refused. We then asked our buyer agent to cancel the contract and she sent us the copies that we eSigned on Jan 24. 

The issue is the sellers do not want to sign the cancellation from their end, which is holding up the release of the earnest money from the title company. Their agent is telling mine that they don't want to sign, but my agent is telling me they have 0 say here since we signed the cancellation papers before the expiry of the due diligence period. Also, their agent put the house back up For Sale status (it was Contingent - No Show). 

Any thoughts / advice / words of wisdom?

(This is in Nevada; if it makes any difference)
