this number is being used by "Ameri Collect" or some nonsense name like that.... their obviously spoofing number because they're not calling from RI or anywhere near it... got called by this number, and two other similar (401-515-xxxx) numbers within the last few days
they spoof phone numbers so area code and exchange are from close to where they're calling... I imagine this has become automated, just a matter of time before all telemarketers and bill collectors phone systems automatically generate a spoofed number local to the area when they're calling, and they'll generate a new spoofed number every time to they call a given number
so much for blocking them... they're all gonna be calling with a different local number every time they call you
