Called saying my entry was picked in a vacation package/gift card giveaway through Target. The callback number was also different from the number that actually called. Was su****ious so I looked up the number and many people have also received the spam call but for different stores “sweepstakes”. Glad I looked into it first!

Caller ID said Fidelity Investments. Wanted to review my 401K. I told him no, that we already have an advisor who reviews it for us. He didn’t push, just said okay just checking in. I can’t say if it was spam or not but when I put the phone number into Google a bunch of stuff came up about****ential scam.

I am getting calls from this number intermittently. There is no identification****ociated with the call and they do not leave a message. Google search led me here. Supposedly Fidelity. I do not have any messages on my Fidelity retirement account. It seems appropriate that they would leave a message there and not with an unidentified call.
