Ultimate Hobbies' reputation for poor customer service has been around for along time.
It is because of this that there has been a segment opened for other retailers to make money, such as SpeedtechRC. As for nitro, they're just as bad in that department as well. If you ever are in need of nitro goodies, go to Kamikaze.
In the past, Ultimate used to be the only place to go to for all the hot RC items at very low prices. That time has been gone a long time ago. If I were you, I would have left everything behind and shopped elsewhere.
