They've started calling me too. If you hear no one when you pick up the phone, chance are that the call is from a telemarketer that's using a dialer. I just hang up.
This is BCR , and they use the B for "bureau" to sound real legit. They call, for T -Mobile cells. (up to 10 times per day!) They leave no message. If you call back, and they are rude just hit 0 on the operator call and it will get transferred to an english speaking professional who will at least explain what it is about.
I have received several calls from this number or another which is BCR on caller ID. Tonight told them to put my number on their DO NOT CALL list. THey asked if I was Holly ------- (my last name). I'm not. They verifed my number. I then looked this number up to find it is a collection agency. I don't know who this person is but the collection agency has my number for her.
