Looking for workshop to fix rear wheel alignment!

Hi guys, any one got workshop to recommend for fixing or repairing of rear wheel alignment?

I bought a new set of rim and tyre and went for alignment, my rear left wheel have displacement of 0.7x.
And the shop says they dont know how to do for rear wheel as the bar or chasis is fixed.

Any one got same problem before? Can recomend where?

Its causing problems of that tyre wearing out VERY FAST.
Now i can only tahan by rotation every 8kKM.
