Anvil Special order case for Mackie PPM1012 Mixer

After buying this American made Mackie PPM1012 mixer several months ago, the first thing I did was do an online search for a heavy duty American Case. I was directed to Hybrid Case Co. and ordered their best case for this mixer. It didn't work because it wasn't deep enough to allow the case to raise (ratchet up) or descend back in into the case due to the depth of the mixer rear. I returned it but they didn't want to custom build one for me. At that point I called Anvil Case Co. because I have several of their nice cases and they have a great reputation. I explained my issue to the very kind and concerned sales rep. We agreed that the case needed to be custom built and agreed to add 3 inches to the back of the case. I paid extra for a custom case and waited 5 weeks for it's delivery to find my custom order was ignored and I recieved the same basic case as I got from the other Co. :-( The Anvil rep confirmed I had custom ordered the case to be 3 inches deeper in the back from his notes. I have requested anvil to make a satisfactory adjustment on the price since I will have to modify the mixer by removing 1/4 inch from the rear chasis lip, or build another case as I ordered 3 INCHES DEEPER in the back. This video confirm s my issue with my purchase. I trust Anvil will make this unfortunate mistakle on their part right with me. Anvil has suggested I return the case to make the back removeable but that dioesn't give me what I ordered. I trust we can resolve this.
