Terrible Customer Service

I placed an order for a system on the 9th of June and it's been 16 days and I have not received it yet.  I have reached out to customer service and they told me I should have paid for faster shipping.  The package is sitting at the Fedex warehouse with a shipping label problem   I tried to reach customer server at Simplisafe a few times only to be on hold for 20 mintues and then hung up on with no follow-up call.  I called customer service again I am on hold again for 12 minutes and counting.  I am so frustrated, I get constant emails asking why my system hasn't been set up yet.  I am going to have the items returned and go with one of their competitors with better customer service.
