Four wheel allignment issues, any advice?

Hi guys, so I got my four wheel alignment done, company is quality car service in Milton Keynes, they charge £150 for geometry alignment with readings, but had a £100 off voucher (was never gonna spend £150)
Anyways, before it went, the steering wheel centre was at around 1 o'clock position.
They took it in, and they said would take around 2 hours........ 7 hours later, still no call, I had go phone them, they said its ready.
I took it for a drive. The wheel was now very slightly to the left, so closer to 11 o'clock position, when held straight, it veers to the right.
I took it back in yesterday, they said would take about half an hour to adjust.
I was waiting for 2 and half hours,I then needed my car back, they said, they are having trouble aligning it, don't know why, it's now at 2 o'clock position so worse, I'm taking back tomorrow and leaving it with them.
They said it could be bushes worn but I'm sure it wouldn't that much out? Plus I can't feel any knocking from suspension or when turning.
Any advice on what to do if it still comes back tomorrow not done? I really dnt have much money at moment as I was made redundant couple months ago, still searching for a job. Car is 2003 8p1 2.0 tdi bkd 140 158000 miles FWD
attached is readings and tread value
Thanks

I mentioned this to them, said just put the wheel straight, however they said there was more effective........ I failed to ask what there way was, I got a call from them sayin there machine has gone off for calibration, so gotta take it in next week, funny thing is, my mums, and brothers car went in to have same thing done, all three cars steering was off. I will speak to them when it goes in next to adjust it all again

I didn't pay £150, only paid £50 with voucher,, would never pay £150, but the looks of it, think I should have, I'm not to sure, Everytime I called to ask for an update, I'd get ' we are just doin the adjustments'

I sent a freind down to ask if they able to do his allignment to see they say, he only lives down the road, they said the machine is gone out for now, so I guess that have actually sent it off for calibration, I will drop it back to them when the machine is back and see if it gets sorted.... If they say its my car, which I doubt due to how much it kept goin out of alignment but first time they got it close, I will then take it else where, ill give Northampton and monkfish a shout, see what the prices are and see which I can afford, if another company gets it sorted, I will then ask for my money back, I call quality car service about an bout an hour ago, regarding why rears wernt adjusted, there answer was that it was still in tolerance so no need, looking at the attachment, although it's apparently in tolerance, i will ask them get both sides to equal reading when it goes back in next week.
It's just ****** annoying right now drinking with steering at 2 o'clock position
