So I have successfully ported out from singtel to circles life when my contract ended. I paid any outstanding bill and thought that was the end of it. The issue came next, I was shocked when the following month singtel bill me for porting out about $40-50+. So far I have never been charge for porting out or porting in. So I am curious is this normal or I can safely ignore the bill? I cannot trust singtel because they used to charge and bill me anyhow for something I never subscribe or use.
