I have been receiving text messages from a company called CSW, they say that they provide Ringtone Timers. I have tried to text message them back, but I get an invalid number. The message also asks me to contact them by email using the address "[email protected]. It does not exist. Should I notify my T-Mobile server? How else might I make a complaint?
I had no idea that I was signed into this service. I gave no authorization for these charges.
Please advise. Thank you.
