One of my work mates, who knows a lot more about cars than me, took my car for a drive and mentioned that my wheels need an alignment as it was pulling to the left.

I'd probably noticed it a little, but hadn't thought much of it, and I had had an alignment done only a couple of months ago. All 4 four tyres were replaced about a 14 months ago (with an alignment done then as well), and they were rotated at the previous alignment 2 months ago. But on his advice I went and got another alignment done (I went to a different place this time).

After the new alignment was done it had made no difference. Looking at the report barely anything had been changed as everything was already within specified ranges (with the exception of the front left caster, which they informed me can't be adjusted on my model of car and that was only 0.08 degrees out of the range).

I informed them it was still pulling to the left so they said to bring it back in. When I picked it back up the second time, the person who worked on it wasn't available to tell me what they had adjusted, but it did seem better.

I phoned this morning to clarify what the problem had been, and they said that they had swapped the front tyres over. I knew they hadn't done this as I recently had a front tyre puncture repair, and there was still a visible chalk mark indicating the tyres hadn't been swapped over. Then they said they would need to double check what had been done. After that they said that my tyre pressure had been low so they had topped it up. I had inflated the tyres to the recommended 36psi before I took it to them, so I went and checked and found all they had done was stick another 10 psi into the left front tyre (making it 46psi). I'm not happy with having one tyre over inflated like this so I have dropped it back down to 36psi.

I'm not quite sure what I should do from here. I don't want these guys to touch it again, but I don't want to throw away good money after bad by taking it somewhere else if the alignment isn't what is causing the problem.

It's not pulling super hard to the left, but there is a noticeable drift if you let go of the steering wheel (obviously the greater the road camber the more obvious it is).

Also, should I be asking for a refund? On one hand (according to the report) it is mechanically aligned, but on the other hand I feel like they didn't really know what the problem was and so didn't actually fix anything so "cheated" by just over inflating the tyre to compensate.
