Hi
Excuse me but I need to get this out.
Why didnt you think about their business process before ordering?
If you had taken the time to do some homework before ordering from them you would have landed
http://www.rcindia.org/rc-outlets-and-resellers/very-bad-dealings-with-thehobbyshop-in/ which is pretty self explanatory thread and would have helped you in deciding whether to order from them or not.
Anyways post in the thread and see how it goes meanwhile try to contact them in every way possible. You didnt mention order date or anything, so my point is dont be in a hurry. Give a 2-3 days slack after ordering to anyone for that matter.LHS's are not myntra or amazon etc(but some serve you as good as these bigwigs.
And next time please ensure that you do some kind of research and look for reviews before ordering online. A list of LHS's .
