Scam/Fraud
07 Oct 2025
Claimed to be from 3 network offering cheaper deal than my current contract. I am not with 3. They said the companies were merging, which I believe is incorrect. They stated I could check on Google. I said I could but it won't say they are merging on there. I told her to tell me the next line off her script but she claimed not to understand so I explained and she huffed and ended the call

Hung up as soon as I answered. Can only assume they are goading for people to call back. They left no voicemail nor sent a message. Likely scam / fraud.

Incompetent spammers. Could hear several people jabbering in the background on their calls. My personal spammer was almost inaudible. She asked if I could hear her. I replied that I could mainly hear everyone else. She then hung up, so I never got to hear her lies.
