Message to Social coupling
I will never do business with a company who makes me pay, through a charge for a text message, to read their advertising - never!
I reported a spam Text message from +1-415-640-1691. AT&T Free Message responded "We could not identify the sender of this message with the supplied information. Please contect AT&T customer care for additional help."
I do not have any additional infomation about this text message or its sender. I hope you can put him/her out of business.
