    Missing one of the items I ordered!

    Posted by Anthony Szpilka on Aug 12th 2019

    I placed a very simple order: for 3 helium gas spectrum tubes. Not only was the shipment a long time arriving (it needed to be back-ordered, so that it failed to arrive in time to be charged to our 2018-19 fiscal year), but, when it did arrive, only two tubes were packed into the three boxes: one was empty! I contacted customer service about this several days ago, but have heard nothing back... We'll withhold payment till we receive the complete shipment.
