Just got a call from this number, she said she was from Design Center asking if I am interested in estimates anytime in the near future, I said no, she kept asking "are you sure ? blah blah blah"", I said no thanks and hung up on her. How annoying ! And yes, she is calling from a cell phone. She sounds fishy to me, probably just a way to scope out your place so they can rob you. Unbelievable.
This caller has called me several times as well. I haven't picked up and he/she/it hasn't left a message. It said Wireless Caller and the number. I will report it to DONOTCALL but my guess is that the number is spammed.
