I've never had so much trouble with setting up an automatic payment for anything. So frustrated I've given up, especially after seeing your post, lol. Cheers, much appreciated!
If my credit expires on the 31st, wouldnt i always want it to recharge on the 31st so you get data rollever. As if you recharge on the 1st I beleive the system think you let your account lapse and data will not rollover
