Order tracking

[Mosquito66]

I placed an order on March 10th and got immediate notification (on this site) of payment acceptance.The order was for FLM parts. Got no emails warning of backorder issues. Ten days later, the order status page posted that my order had shipped. Seven days later (today), still no package. Meanwhile, FLM parts ordered from a competitor arrived 2 business days after placing them (also ordered on the 10th). I even had to exchange an FLM item which took a speedy 4 days. I've sent 2 emails requesting info, both of which bounced back to me after 48 hours or so. Is this typical? Who can tell me where my order is and why it's taken 17days thus far?
