Unsubscribing DiGi SMS Promo

I have written in to DiGi on their irritating SMS campaigns few days ago. Here is the reply. Hope it helps any of you who has the same problem as I do - which is silly DiGi promos flooding into the phone. (Click on image to view larger version)


The bad & sad news is, an error message returned on the phone saying that it's not a valid 'message code'. I re-sent it and there was no reply. Let me know if the solution given works for any of you.

Something I love or hate ....
1. DiGi Customer Service responded quick enough, within 2 days.
2. The solution doesn't seem to solve the problem with error messages.
