Answered it, it was "Ariel" calling to tell me how she can lower my monthly electric bill, by me purchasing the solar panels that she was attempting to sell. When I told her I wasn't interested and would like to be removed from the calling list, this person muttered a curse word under her breath and abruptly hung up on me.
The individual who calls is relentless at attempting to set up an appointment. He was very professional and invitational up until the point I resigned to meet. At that point, he made "cracks" of a personal nature that were offensive in what I believe was an attempt to invoke emotions to have me "bow up" and defend my manhood. What a tool! Regardless, I was very much interested in the company until that point, even asking for materials. If a company's products sell themselves on quality and price, ancient tactics such as these are not necessary. Therefore, I am left to infer from its customer service representative that this is a shady business.
