I ALSO made a grand error and ordered somthing from Hobbypartz.com and same experience ... no order updates received by me...ZERO customer service/support.
Their phone support <took 45 min to get through> could NOT answer my question about their own product.
their email support/sales reply was a automate " go to http://help.rcdiscuss.com/
" All Automated..confuseing...a downright waist of MY time & still no reply !!!
I Cancelled my order b4 it was shipped and that was confirmed through email....and ws told my account would be creddited......they shipped it anyway ( After I ordered it's replacement from someone else
