Who called from 4083378043

Some company contracted by Comcast.  Doing survey why I discontinue service with Comcast.  She spoke very fast and some questions were tricky or loaded.

Called. Left no message. BLOCKED!

Caller ID says SSI and they have used 4 different phone numbers - annoying! All 4 now blocked!

Says SSI??

It's not Social Security-there is a survey company with the same initials-Survey Sampling International. Here's a link to a link to report them: https://en.wikipedia.org/wiki/Survey_Sampling_International#Complaints
