Kept calling my mobile phone over & over within a span of 3 minutes. Did not leave voicemail. I blocked my number from showing on their caller id & called back to tell them to please knock it off, but my call was repeatedly rejected. When I unblocked my number, however, some lady answered by immediately saying I'd been applying for jobs on their employment website without even giving her name or a company name or saying hello. I told her I haven't been applying for jobs or visiting employment websites & I'm on the do not call registry. Before I could even finish my sentence to tell her to take my number off her list, she interrupted me, mumbled something snide that I didn't quite catch, & hung up. All things considered, it sounds like a scam to me. At minimum, it's harassment to have continually called back & kept my phone ringing for nearly 3 minutes straight.
