Six entries on this thread and 4 of them are shill posts. A 66% shill rate. Which spells scam to me. Similar to those 800 number scams targeting customers of large-scale financial institutions.
So you got a legitimate call. Everything was just fine. You weren't scammed. So tell me--who did you go to an anti-scamming site and post the number? Most people post here if there has been an attempted scam or someone has been scammed. In your case everything is just fine. Again, why post here if things fine?
Simple solution to prove you are telling the truth. Give us the legal name and address of this company. If you don't then it proves that you along with the rest of the posters in this thread that claim the call is "legit" are lying.
