What is the definitive way to block Premium Texts from 700038340 - STOP /STOP ALL is not the answer
So, now I've become a victim of charges on my mobile bill from a premium text sender, and I don't know how to definitively go about blocking it. I have tried sending STOP / STOP ALL, but the messages is not getting through, presumably because the country code has been cunningly disguised. Am I being stung every time I try to STOP the messages as well? Currently, there are 4 items on my bill, and they appear to be reliably transmitted on the same day/time each week. So what is the answer to getting this stopped?
