Who called me from this phone number (844) 891-0355

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.

Left a voicemail saying her name was Naomi with T-Mobile and that I qualify for some new offers. Asked to call her back at 844-891-0355 but spoke the phone number really quickly both times. WAS NOT T-MOBILE.

Caller ID says T-Mobile. Caller spoke English with American accent. Background sound of a call center. Asked if I would be interested in their great offers. I said no. Caller was not pushy at all. Also it was Tuesday which is T-Mobile's promotion day. Next morning the same number rang once before they hung up. I called T-Mobile customer service and they accessed my account and said no interactions were recorded in their system. They suspect it is a scam.
