    “Supertalent1982 has failed to communicate with me and has not delivered anything to me. After numerous conversations and product demonstrations they are now non-responsive. They are stealing from me and I would like their account to be thoroughly investigated. They should not be allowed to work on any additional projects. I've tried contacting them through numerous channels and given them ample time to respond to my requests. I really hope there is something can do to either help me with this situation or serve justice to this fraudulent user. Thanks”
