After weeks of getting calls from Quality Construction in Aurora, CO from their 303-495-1972 number, I looked up their office number and left a VM at 9:50am 2/5/13 asking them to take my name off their calling list. At 1pm 2/5/13, I received yet another call from this company trying to sell me home repair services. I told the caller that my number is on the federal do-not-call list and that he is breaking the law. I then went online and filed a complaint with the Denver Better Business Bureau. You might consider doing the same. The BBB generally gets results.
