We get calls like this all the time. Here are some tips on how to avoid answering these types of calls:
► Don't have a land line. But if you do, just forward the calls to an answering machine.
► Never give out your phone number to anyone.
► Keep a current list of friends and family within your saved settings.. IE xxx-xxx-xxxx means thats Uncle Tom calling etc..
► Never allow anyone to use your cell or home phone, what they do is use your phone to call a telemarketer etc to register your number without you knowing it.
► If the number doesn't look familiar to you, chances are it no one you should be concerned with.
Just thought I pass along these tips which have saved us time, money and the head ache associated with unwanted calls.
