Offer up has no customer support. That department does not exist. Be very careful when selling something nationwide and putting your money in this application. A lot can happen, and there is no one at offer up that can help you.
I've been dealing with a major situation for a few days now and the customer support team has been outstandingly! I've been getting replies within 24 hours. I'm not saying your all wrong but to make a blanket statement like you are is in fact making a false one. Along with the support team, the Community Manager @Mj_206 has been a great help as well.
