Phoned SQ KrisFlyer today and cancelled 2x J SYD SIN DXB which were redeemed from my account - points credited immediately, had to pay cancellation fee separately and refund of original taxes, fees, surcharges will take 3-4 weeks. At same time cancelled 2 X J DXB SIN SYD which were redeemed from my partner's account. All done but then received a call back within minutes to advise that given the originating point of this ticket was DXB, refund of points would have to be handled by their DXB office??? Reason given was because we had altered the original ticket - originally DXB SIN then we married SYD with a two night stopover - and told this could take 4 - 6 weeks!!
I was hoping to rebook our new itinerary HND SIN SYD from each account tonight as we will have some 'change' from the other itinerary but have had to transfer MR points to expedite the process.
