I get many spam/scam calls every day. I only answer if I know the caller. They usually don't leave a message which tells me they are not someone I know or having a legitimate reason to call. They are trying to sell me stuff, or somehow trick me with a scam. My phone alerts me when a caller is a suspected spam. I think people would be angry if you try to call them because they left a bad review; it would be considered a violation of privacy. Perhaps your company should provide a product satisfaction guarantee and toll-free Customer Service number in your product description.

Hi. I have made some changes which help to make the sentences flow better. One of the most obvious errors was in using conjunctions like "and, but,because". These words are meant to join words and shouldn't begin sentences. However, your entry is very well written. I liked the use of "vigilant" and I understand what you meant that they work hard on not answering the phone. However, in this situation, suspicious seemed to be more appropriate. Keep up the good work!
