Received a call from this number. I answered and they hung up on me. I called back and got a message stating that the call could not be completed as dialed, even though I called from my cell phone. I assume it's a spam call.
A Google search brought up no listing for "St. Jade's" but there is a Jade luxury resort somewhere. St. Jude's is a children's cancer hospital. I am betting it is a scam call.
