company that buys old debts for pennies on the dollar, calls from mult. #s begin. w/ 714-actually does not show any area code & says "unknown caller".It does not matter that most of the debts are far past the Tx. statute of limitations (4 yrs.) - they cont. to call & say there is no law that can stop them-that  stat. of limit. only means yoiu can't  be  sued for the debt if you have not been already. Plus, they hang up on  answ. mach. & when you are nice (or dumb) enough to call back, they put you on hold forever, then ask  what your phone # & name are (even 'tho they have your # on caller i.d.!!)
