Extremely frustrating. Especially if I just unlocked a new series, and accidently backed out too far. I then have to wait a while till I can reload, and purchase the new car and wait the HOURS for it to be delivered.

Galaxy S4 should have no problems at all. I play on a Galaxy Note4. Strangely enough, I had a lot of trouble today. Usually I'm fine unless the wifi is spotty. Try the other stuff I suggested above and/or submit a ticket. Your situation does sound frustrating, I hope you can get it worked out!
