Hi,

NP is an online company that's why we have support forum here to help and live chat. Sorry that we can not increase our phone support because of the price we offer. We have 5 customer service working non-stop 12:00 to 7:00pm. If you really need to talk to someone then please call during 6pm to 7pm pacific time same number. If you want to know if we have the model instock you can ask me here.

Thanks
John
