I am blocking this number on my cell. My number has been listed with donotcall.gov since 2006. I only give my cell number out to family, friends and acquaintances. This number is not any of those.
Never done business with a JBC Holdings. Scammer of some sort, I presume. Don't owe anyone any money, so I doubt it is some bill collecting degenerate, but I still have no idea why this person thinks it's a good idea to call someone on a DNC list. Reporting them now.
