Stock bed shaped like a U

I finally got to the part where I setup the beacon for the first time and create bed mesh. VC4 500 IDEX. The bed has a serious physical dip on the right side. Straight edge confirms the valley on the top and the straight edge is like a see saw on the bottom hump. I have contacted ratrig several times with no answer. What do I do from here? I refuse to stick my heat pad or magnet to this bed as it’s so bad and you can visually see the dip without a straight edge. Here’s my graph.
