Telekom autopay via MBB2Amex got transacted yesterday, 16 October, a Sunday. Not just 5x points, should get 5% weekend rebate too. But I think depends on the Telekom billing date, of mine is 10th of every month.

You're right that we can't time the autopay, but what I meant was that my Telekom billing is on the 10th of every month, while my Telekom autopay normally transacted on 16, so whenever 16 falls on weekend, my MBB2Amex autopay will give me 5x points + 5% rebate, otherwise when 16 falls on weekday like Nov & Dec 2011, I will still get 5x points.

Generally I have no problem using Amex at Shell petrol stations. But in the North-South Expressway, at the south-bound Shell Tapah (KM333), my MBB2Amex has failed for 2 different trips, whereby I tried 3 times each trip. Failed at the pump though, didn't go to counter.
