This is a scam. They place an illegal call to a number on the do not call list. Then they illegally have a recording, but no human, on the phone when you answer. They claim that they will provide you with a free web site, and threaten to provide it to your competitors if you do not accept. When you get an operator, they tell you that they will set you up for 30 days free, then charge you for their supposedly free service.
"Google-optimized websites" - scam telemarketing, no live person. When you call the number a recording offers to remove you from the phone list but somehow 'surprise surprise' their computer can not seem to get the number right when you enter it. Then 'surprise surprise' within 5 minutes of attempting to remove your number using their 'automated' system' you will get another recorded sales call.
Unethical marketing practices & this would be that LAST company I would use for these services, if I needed them.
