Non existent customer service, should report to BBB.
Tried unsuccessfully for a matter of months to schedule an appointment here for a gift certificate I received and never received a callback. I ultimately ended up getting a refund on the certificate (if you call Groupon they are aware of the less than stellar service that is being offered and they will refund your money). I would not recommend this business to anyone.
Shame on Zenful Monkey!!.
Unable to use Groupon for this company. Tried sceduling online. No appts avialable after mentioning Groupon. Left several messages with no return response. For that I would not recommend doing business with this company!
