We've been with CC for over a decade and found them excellent for many years. Recently, there was a bug in one of their plug ins and we lost almost 3000 subscribers overnight. CC has told us they are working on it but they have no timeline to fix the issue and suggested we manually add the 3000 subscribers one by one in the meantime. This has been going on for 30 days and all they can say is 'we apologize for any inconvenience'. I feel with tens of thousands of customers they are now too big to be able to provide adequate customer service.
