Hours of Operation:

 Due to overwhelming call volume, we will not be performing order status checks on any orders still within their estimated lead-times.  We will perform status checks on those at the end of or after the estimated lead-times.  Email requests are faster as we're able to address them sooner than the phones.

Also due to overwhelming call volume, voice messages left with our Customer Support number may take quite some time to get a response.  Our phone system sometimes overwrites voice messages left by customers so please either try again or send a message to sales@x-caliber.net (as this email address can be checked and responded to anywhere by anyone here), you're far more likely to get a prompt response with an email inquiry than via phones for the time being.

Before placing an order, please double-check to ensure all details are correct beforehand!  Delays involving order change requests continue to increase.
