Caller name: Have no idea
Caller type: Unknown
Called on my iPHone 6 during work. I hit the lock button to silence ring, expecting them to leave a voicemail when I did not pick up the call. Seconds after they ended the call, they called back. I hit lock. They called back. I hit lock. This happened SIX TIMES IN A ROW - each call back within seconds of the prior one. I stopped my work and selected 'Block this caller'. HOPEFULLY this will work. Am already on the government 'don't call' list but it seems to be doing NOTHING to stop ANY of these annoying kinds of calls.
