Got a call at 11:47 pm (ALMOST MIDNIGHT) last night. Answered because I was concerned there was some sort of family emergency. A woman said she was from T-mobile and that they had received a call from my number. I said I DID NOT call them. This morning when I checked my call log, the called ID said "Invalid Number"

Mine was from Walmart Family Mobile. They use t-mobiles network. It has to do with getting authorization from the account primary. They don't leave a message for security reasons.

5 hangups in less then 2 mins just now, no message left

Just got 2 calls from 800.937.8977. I didn't answer (don't answer ANY numbers I don't know, and no msg was left. Right after that, my daughter-in-law called to say she was trying to make a change to her phone (T-Mobile family plan), and the call WAS legitimate. Then they called back a third time wanting to validate her request; I suggested they leave a msg in these circumstances.

this number keeps calling me and hanging up.  i would like to know whom it is.

Received two phone calls back-to-back and then a voice message from this number.  The message was concerning something about a T-Moblie Account, which I do not have. I tried calling the phone number back and nobody answered, not even a robo answer.

Just had call from 800-937-8977
Did not answer and no message was left

This numer left a voice mail on my cell.  Could not understand much of what the woman was saying, about the only thing I could discern was T-Mobile something or another.  Since I do not have T-Mobile, wonder why they might be calling other than to sell or to scam me!

Lady with an asian accent was trying to get me to divulge more information.  Told me my account will expire in 30 days and kept repeating what I had for data left on my plan.  When asked where she was from multiple times she finally said she had a wrong number and hung up.

Need to know where is that number is coming from and the address of the store

T-Mobile customer service's outgoing line.
