Who called from 8105553528

Caller ID "DIR ASST   MI" called.  If I need directory assistance, I use the web.  Can you say blocked?

Today I got 8 telemarketing spam calls and this one as people above said it's from different number than calls I got before but the same guy with bad accent and pronunciation.Do they have special days to spam because there are days I don't get any spam calls and others so many.
