Some guy with a heavy East Indian accent called claiming that I have had something installed by his company / and or am using one of their services. The background was very noisy making it difficult to know what he was talking about. I called the number back with a message advising me that this number is out of service. Most likely a voip phone.
The caller was peddling his duct cleaning services. I told him to take my name off his phone list and that I was on the Do Not Call list. Annoying to no end.
