Received a promotional mailing from Spectrum. ( I have gotten the sam mailing aprox. 8 times so far) When I finally called the number listed to get details, the customer rep.would not give me an answer about what specific channels were included. ( I know it sounds incredible). I asked several times but they were evasive. Then they told me that I was currently getting extra channels because the cable installer had made a mistake and that I needed to upgrade in order to get a similar package to the one I already had. When I informed them that I was given that discount through their Customer Retention department , they eventually agreed but said "They shouldn't have done that!"
All this hassle just to ask a question about a promo that they had sent. I declined and will try my best not to deal with any Spectrum customer service department again. Be wary of their promotional offers.
