Such a big company but no customer service #. Been using it for 5 years now, increased my business over 500%, sales are now in the millions but no account manager or any help except chat. They can shut your business or freeze it whenever they want (I know because it has happened to me), even if what they say makes no sense and they CONTRADICT THEMSELVES in their emails. Takes 24 hours for them to email you back when you have a serious issue, and they still don't resolve it even when you do exactly what they say. My advice: avoid this company like the plague.
