Hello Steven, We checked in our system that you placed an order for (2) DT-135F SIEMENS units on 05/05. This order was shipped on that same day and the tracking number 1Z58079W0319898287 says these products were delivered at the requested address by 05/07. We tried to contact you by phone and email, but unfortunately we haven't been able to reach you out. If necessary, we can also send you a proof of delivery provided by UPS. If there is anything else we can do for you, please let us know. You can call us anytime at (480) 977-3555.
