Complaint Review: Amazing Pet Expos

I was contacted by the representative of Amazing Pet Expos via Email a several times offering me a "last chance" discounts for the spaces at tshopper related trade show in DC. After speaking with them on the phone they convinced me to get a deal for 2 spots for $800 instead of 1 spot for $500. The trade show was scheduled on April 5 th in Washington DC. They canceled the event a week prior the event. A couple of weeks later they informed me that the event was rescheduled, and would be held in Maryland instead, in fall. I called them a numerous time demanding the refund explaining that the only reason I signed up was because of the location (Washington DC) . They refused to give me a refund, first.  Tired of being redirected to different representatives where I left numerous voicemails without anyone contacting me back, I submitted a review on the social media. Immediately, I got a respond from Sheila, who was apologetic and promised me the refund, however, she redirected me to another person Jenn Reiss. Jenn reassured me that my refund would be sent out In May. I waited patiently. When I did not receive any refund I contacted Jenn Reiss again. First, she told me the refund was issued, then she came up with a different story saying that the refunds were delayed. Then, she told me that she would personally take care of the problem. 2 weeks later, still no check. Called her, and she came up with another story saying that she was away. finally she told me that she did not know why no one  had sent me the check yet. She promised to call me with results in an hour. A couple of days later, no call from Jenn Reiss, no check. In addition, one of their representative also mentioned on the social media that they did not have any outstanding refunds... When I said it waS not true, that I Was still waiting for the refund, he/she got all mad and threatened me with their lawer. They keep redirecting me to a different representative, who comes up with a different story. I am not even sure if this company is legit.
