Called my cell phone number and since I didn't recognize the number I didn't answer. They left a voicemail message saying this is the final notice about changing my credit card interest and to say "yes" or "press 1." Yeah right. This is a scam so I blocked the number.

IRS SCAMMERS trying to steal your refund

They called my cell phone number.  I didn't recognize it so I didn't answer.  They didn't leave a message.

I showed three missed calls from this number all at the same time. No message left. Blocking...

Received a call from this number, didn't recognize number so I didn't answer. I called back three times from my work phone & all three times there was a a message that said; "Call cannot be as dialed, please check the number & try again" this told me it's a scam so I blocked number.
