What you could do if it's worth it, is glue and clamp the affected area, drill out the screw holes and glue in hardwood dowels. Once set, drill screw holes into hardwood dowels and reassemble.
Or start saving up and speak to someone about a custom built desktop
Or, run down and pick up a tupperdore
Or run down and get a coleman cooler for a coolidor
Or.....
You do have options if the vendor doesn't take care of you. Hopefully they will and this is all for nothing.
