Dear Quik
Do not make conclusion that fast. As far as I'm experienced of, the accrual points will still be given to you eventhough at the point of travel with no Enrich card, say six months ago, they would still give you points, subject you have all the ticket snubs and boarding passes with you. It happened to me but then again I stormed their HQ just to hand over the application form. At that time, I brought with me the ticket snubs and boarding passes just in case and guess what, the lovely personnel there said quote "well..give us the snubs and everything but don't expect to get it back.."unquote. It was a worth trade-off
In all, just be nice and they'll be even more nice to you. All the best,
