No responsibility taken for breaking a part on my car

Last week my husband took my car to hi q in athlone to replace a cv and do wheel alignment. We noticed the car still pulling to the side and not driving smooth at all anymore and we could only take it back today Sat, 20 Jan17. We then noticed the level sensor was broken. I called to speak to the maanger who came up with several story to back themselves up. He then basically implies that we broke it. I refuse to pay for something I had not broken. Note that this part is at the bottom of the car where the cv was being fixed. How ironic! So we lifted the car up and fiddled under it to break the part off ourselves? One of your workers had no knowledge that this part had to first be removed before replacing the CV but they thought they would bypass that and clip it. Now today they wanted to super glue it??? I am disgusted because besides the fact that not even the manager wants to take responsibilty that one of his workers did infact break the part, the wheel alignment is still not fixed and we driving around looking for someone to fix it. Someone is going to pay to replace the level sensor and it will NOT be us. Then they blame the thread on the tyre which was never a problem before bringing our car to you. Ever excuse in the book to come up with! We hear how u bamboosle other customers while we standing there and we won't take this laying down! Silly mistake like this costs us a fortune and we will not be liabe to pay it! Can someone pls contact me other than the uninterested manager at athlone branch that giggles while I speak to him on the phone. Just because it's not your car doesn't mean you can mess around with people and do back door procedures to get the job done. If your worker did not know what they were doing then they shouldve said so and we wouldve gone else where. As simple as that. But it's easier 5o take people's money and not care about their property. I am expecting someone to call me soon. ********** 875
