Kept calling them and emailing them. They just won't send me back my Buyer's answers. They kept telling me that they would send me the answers "by the end of the day". Well I don't know how long your day is, it's been a week now. I've been told to wait on the phone and so I did, they let me wait for 15 minutes and hung up without getting back to me. You need to take full responsibility if this jeopardises my sale. Worst experience.
