Hi Guys,
it seems that I am not the only one person who had bad experience with Sheldons Hobbies.
RC-Zombies
It may doesn't sound right to you but unfortunately it happened.
When I called back the rude guy, I asked to talk to someone else and he replied that no one was there...
In my understanding Sheldons hobbies doesn't care about their customers by being so rude, so I won't beg for being one of their customer and will never call them back even if Jaime and Roger are back...
I will create this thread in electric forum, I think it is worth people to know about that.
