I've submitted a retro-claim over 4 months ago, which still hasn't processed into my account yet. All my subsequent email enquiries are not responded at all. Their customer services are rather shocking to me - No efficiency, nonfeasance and total lack of basic etiquette.
My complaints have been outstanding for quite a few months and still not been attended to yet. I am so regretful of joining Krisflyer at the first place also because it doesn't reward as much as other ones.
