Help! Can't remove stripped lug-bolt from W124 front wheel

[ke6dcj]

Had new tires put on the W124 wagon, asked them to hand-torque
everything, and when I got home, and let the car sit overnight to check
the wheel lug-bolt's torque, I noticed one would not snug up.

So I tried taking it out, no dice.

I'll be calling the tire shop (America's Tire Shop, aka, Discount Tires,
Inc.) Monday, but if they don't offer to fix it correctly, how should I
proceed to remove this lugbolt? I'm thinking a replacement hub will be necessary.

Thanks,
