7726 SPAM reporting not working?

I am pretty much a daily recipient of spam by text. I was routinely in the practice of forwarding these to 7726 to report the numbers to AT&T. I would forward the text, then I would get a response from AT&T to then send the "number" from which the text had come. Once I did that I would get an acknowledgement in that my report had been received. In the last two weeks I have not gotten ANY responses to my forwarded spam text messages. Is the service down... or should I be worried that I am hacked or something?
