Called to place order for ATT/Delta program on 3/28. Received letter dated 4/11 stating Skymiles program enrollment 'unsuccessful'. Called the ATT rewards program dept at (800) 547-0403. They added my Delta account and said to wait 6-8 weeks for first 1000 to post. First bonus miles posted on 5/9 - 1000 for 3/28 and another 1000 for 4/28.
