Re: [kaustik] What is a complete rig?
Did it include a canopy? Or just a container?
Different manufacturers package the gear differently.
For example, Asylum and Morpheus include a stash bag and PC with the purchase of a "complete" harness/container system (i.e. container, risers, toggles). Apex doesn't include the stash bag and gives you a discount on the PC (rather than including it). Squirrel gives a 50% discount on both stash bag and PC, but includes neither.
If you upgrade to include the canopy in your "complete" (term used differently by different companies "system" then the package changes, too (for example, Apex now includes the stash bag that you had to pay for if you just bought the container).
If they told you a PC was included, then sure, contact them. If you just didn't read the details of your purchase, then I'd say it's more your fault than theirs.
