Complaints about Phone Numbers844-891-####

Caller sounds recorded does not say who they are and is threatening me if I do not call them before end of day today.

Received a call from 844 8910355, on a Saturday afternoon. They said they called from TMobile and the caller ID displayed as TMobile so I thought they were registered in my contacts. There was noise in the background as if they called from a call center. The person who call had an American accent. They had my name and last name and said is this (name and last name)? I said yes and then they said, it is TMobile on a recorded line. We contacted you to go over some promotions that your account qualifies for. I asked to send me an email and never received anything from them. After I hung up, my phone did not have signal and my internet connection was lost. I called TMobile and they said they did not contact me and that that phone number did not belong to TMobile. I called that number back and there was a voicemail saying thank you for contacting TMobile. We cannot answer the phone right now. Please be aware of this scam. I never answer the phone but saw the called ID as TMobile and thought it was a call from the same number I had on my contacts.
