MD Good move and great advice for all. Solicitors and Debt Collectors all use VPN's and other national phone number providers. They do this to in many ways because you may have lived, have a relative or currently live in a certain area of the country. It could even be the area code of where your employer has a home or regional office. The peddle everything from bogus extended auto warranties to junk debt buyers using hard pressure tactics.
Regarding this number I didn't have it in my database and tried to call it and it basically instantly hangs up. This is a clear sign that the caller is from a call center and trying to hide their true identity. This is why they didn't leave a message.
In general companies who don't want you to know who they are they have a reason and it is not to YOUR benefit it is someone on the other line wants to use high pressure techniques to separate you from your hard earned money. If they keep calling block their number using a smartphone app or one of many hardware devices for you land line available on Amazon.
After doing more research this caller is Refi Card Services a telemarketer who claims they can "lower your interest rate" They are a scumbag outfit do not share any information with them as their privacy and security policies are unknown.
