In my experience your statement is incorrect.
I booked SQ J from SIN-FRA on the A380.
After inputting my credit card details I got the credit card error.
I called lifemiles, held for about 5 minutes whilst they checked and was told that I'd receive the e-ticket in the next 24 hours.
2 hours later, the e-ticket arrived.
caveat: I am Spanish and had no problems communicating. Experiences in English may vary.
