Thanks Nam, yes I have called AGL twice and asked to be removed. The friendly operators on both occasions confirmed that I have been removed. I have not. I have also tried on several occasions to use the online chat however that was a waste of time as the app does not notify when a response is made to my query. The first time I tried the response was received 30mins after my first message at which point I was absorbed in a movie. Forgive me for not sitting beside my phone in anticipation of a quick response.
The right answer here is for AGL to change your text messaging engine to allow "stop" or an opt out via the text interface as most spam text senders allow. Please don't take advantage of your customers in this way.
