Mcconechys Tyre Service Ltd

I took my car in twic within the month to have the tracking done. it has turned out the person who done it both times, neverput through the books and did not track my laguna properly. I am now having to replace 2 tyres that have only covered 6000 mile and have the car tracked properly. My tyres ae £100 a piece and Mcconechy's are not willing t help on this matter so all in all i am going to be near £300 out of pocket for something that should have been sorted the 1st time
