He told me that he must have accidentally done so while trying to do a talktime transfer. But I'm curious as to how he could have done so, since pressing *116# and *128# are totally different keys altogether.
Anyway, this plan is pretty insane in my opinion since it just automatically renews your subscription everyday and conveniently deducts the money from your prepaid card. So if you are a handphone/internet illiterate like my father, you wouldn't have known about it and how it charges you every single day even though you don't use the service. (Let alone how to "unsubscribe".)
What's more, the FAQ section provided on Digi's website doesn't state "clearly" how to terminate the subscription. It just says the following:
|Q19||How can I terminate my subscription to Mobile Internet Daily 100MB?|
|A19||Dial *116# and Press 2 to Confirm your unsubscription.|
But if you had followed the instruction to the letter, you would have instead subscribed yourself to the Weekly 300MB (RM15) package instead because this plan is numbered 2 in the menu after calling *116#. (There simply wasn't any "unsubscribe" option in the menu at that stage.)
To actually unsubscribe from the Daily 100MB plan, you should select back the same plan by pressing 1 instead (after calling *116#). From then on, there would be an option for you to unsubscribe in the menu. Just follow through with it.
If you ask me, its just plain weird that they make it "sooooo" easy to sign onto the plan and yet so "counter-intuitive" to terminate it. What's more, its "sooooo" user-friendly and "kind" that they would "help" you renew the plan without even asking you about it.
Anyway, I hope that this post would help you in unsubscribing from the service if you or your parents have accidentally subscribed to it.
