Sinking feeling (seats)

[Rufton]

I have no luck farming out repair work; maybe karma who knows.

Had 66 bench "repaired" and covered.
Talked to owner at length about sagging springs in drivers seat.
Owner assured me he would fix the springs.
I asked if he can repair seat so it would accommodate a heavy person; he said he will repair seat good enough for heavy driver.
I asked him about spring repair three times; he assured me each time.

Good news: seat cover looks good.

Bad news: first time I sat in seat (not in truck yet) I got that sinking feeling. I looked under seat and found a broken spring. Owner said tech didn't weld it good. Owner welded spring and sent me on my way. At house, I installed seat then noticed a spring is trying to poke a hole in skirt. I removed some clips, lifted skirt and found another broken (unwelded) spring. I then noticed some driver's side coil springs are shot and not touching foam.

Choices:

A: Order some zig zag springs and coil springs and repair myself.

B. Return to shop in July and see if shop can/will correct broken and saggy drivers side springs.

C. Ask someone above what I've done to offend the repair shop gods.
