I keep getting calls from this number but noone answers; when I try to call it back, the phone rings once, but there is no answer; I am going to save it as a crap call so that I know not to answere it.

Telemarketing scam by company called Thumbtack. Charges fees for business leads that never turn into actual work. Hundreds of online complaints against them as well as BBB complaints.  Phone # is either spoofed or now using cell phones with local numbers.  Caller had foreign accent and may well have been calling from outside the US.  Caller ID read: Zone Telecom 207-239-3718
