Just hang up!
Got a phone call today 2/25/13 from this phone number, Google search traced it to BANDWIDTH.COM in Iowa City (My iPhone CID said Iowa City as well) I'm about 99% certain that the male on their end is actually a recording. I was told I filled out a survey for employment (not true) I asked multiple times what survey / when / what company, it responded "even if you didn't take the survey would you like me to create a profile for you?" I asked multiple times who they were calling on behalf of and after multiple long pauses, it would respond completely disregarding my question. I asked "who am I speaking to" it responded " Hello, my name is... blah blah (same introduction as when I first answered)." I asked "what's 2+2" it responded " Yes..." I asked once more "who am I speaking to?" it replied "Please hold one moment, I'm still in training.." I then hung up. Telemarketing like this should be illegal.
same ... sounds like phishing don't give them your information
Same situation as Bob. Got call early in the morning.
Spammer stating I filled out a survey
