Q about my m1 bill i think my last m1 bill should have been sent to my previous address in PGP 3 months ago. (I've already terminated my m1 plan coz i had been using it for two years already.) now i'm not in singapore. and the m1 bill letter hasn't been collected since 3 months ago. (i don't know whether PGP has returned it back to its company or not.) what shall i do? does anything unpleasant will happen? i'll be back in singapore at the end of January next year. thanks for your help. cheers! one more question: i've bought a open ticket (half a year), normally when shall i call the airline to confirm the date of return? a week in advance? two weeks in advance? or a month in advance? thanks.
