SSI (Survey Sampling International) is really a telemarketer. Two calls this week, one on this number and one on 843-593-8149. Latter number also called twice in March, 2014 and both numbers now blocked.
I receive one or two calls a day from this number. I have repeatedly told them I am not interested in taking a survey. If I ignore the calls, they call back later. PLEASE STOP IT! No one in this household is interested in what you are promoting or selling.
