I was not sure who this is, nor did they leave any type of message. So, I called them from another number to see who picked up. The person that picked up the phone was a woman at what sounds like a call center (very noisy background). She answered the phone "did you miss a call from us or receive a letter". I told her I missed a call, then she asked me for the number they called. I told her to tell me. Then she stated they were a very large company and could not know who they just called. I then asked her for the company name. She stated "Fidelity". Which sounds fake. But, I asked her what their business normally regards. She told me they deal in financial services. I stopped her right there. It's either a creditor or one of those bait n switch scam centers.
