I want to know what this service provides as I always get additional charges for it. I got it once before from some 33 number previously and I have already unsubscribe. And now once again. I want to know what this is as I know it's definitely not from me and thus I wouldn't want to pay for something that I have not used. Can I know what is this? And I would like a better explanation as previously, the employees only told me to unsubscribe without even telling me what kind of service this is? All this only happen when I shift to Pospaid Family. Last time, it was all fine.
