I bought two Groupons for Bella Piel. This has to be the WORST merchant that I've dealt with on Groupon. I am also disappointed with Groupon Customer Service. The owner of this company blew me off on 3 occasions without a phone call. I even proved to her once that she booked an appt with me. Then she's called me twice to rebook and thought I was someone else. The tenants that share the building with her said that she always blows off appointments and leaves people waiting. I've sat in the waiting room waiting with appointments before me that were never seen. I am NOT the only one to experience this. My mom and my friend had the same experience. I wrote to Groupon for a refund, but was denied. My friend was rebated. I still have one more certificate to use, but would like to extended the same refund offer.
