Absoloute bunh of useless 763!:773!
Took me 4 visits to get mine sorted a few years ago.
Every time I went they took it off, checked it in a water bath and said nothing wrong with it. Next morning it was down yet again. Totally incompetent.
In the end I set up a video camera overnight just to make sure nobody was messing about with it, sure enough you could see the car wing getting lower through the night!.
Next morning it was raining heavily, I rolled the car back and forth until I could see small bubbles, I marked the tyre with nail varnish and took a video and photos. Took it back again (about 7 miles each way) and showed them the exact place it was leaking, they grudgingly agreed to replace the tyre.
That was KwikFit at Washington, never went there again.
Please excuse spelling/typos. Apart from being a clot it turns out I had one on my cerebellum that's now causing various problems!
