Came back from overseas after away for two weeks and noticed one of my passive Digi numbers was terminated.

It was my mistake as I already set reminder to extend validity before I leave, for the first time I overlooked the reminder and that's it.

I have been retaining the no. for more than four years and it's ending with AABB with just 3,6 and 9.

I just noticed it when I turned on MyDigi app and realised it's no longer listed under my name, I could sense something bad and I was right! Called CS which I know won't help at all, so as expected I won't get back the no. anymore.
Maybe you all will know better, if there's any chance to get back like signing up as a postpaid no. temporarily? Digi Centre in The Gardens is just next to my office, so it's convenient for me to drop by. I know the chances of getting it back are less than 0.1% but if anyone here has any similar experience, then please share.
