With any business that changes management...alot of chaos ensues. There may not be anybody around even checking emails. Have you pre-paid for the crickets? If so, if its a check or credit card/paypal payment...see if its been withdrawn and if not, cancel it. If it has, then definitely continue to attempt to make contact. Have you tried their phone number? (assuming there is one listed on their website? If not, try the business directory online for a contact number).
