They stuck with me until the listing suspension was removed. It tooks several emails, but their instructions were clear.
Price was very reasonable compared to other service providers. You pay one fee and they will work on your case until every option has been exhausted.
If you are choosing from among several providers, give these guys a try first. They communicate quickly and clearly. I would definitely use them again when the need arises. It's a great, affordable service for sellers with no time to deal with the various departments.
