A call centre from India probably (due to the "English" they spoke) presenting themselves as "Duct Cleaning Service" and offering to come and clean my ducts. Only in the background one can hear other agents yealling to other customers.

Got a call from this company (Duct Cleaning) everyday for 4 weeks now. Have told them to take me off their list but yet they continue making their calls. Total calls have added to 52 and counting. These people are relentless. I told them I was going to report them to the police and it does not bother them. I have tried calling them back and a woman with broken english answers saying " no company here". These are terrible people using bad business practices.
