Why i hate tyre centres

[Russp]

My ZT has just failing MoT with a hole in the sill.
When I went into the garage, coastal MoT of sheringham who are excellent the chap said have you jacked this up recently?
Then showed me the hole
I recently had two Avons fitted at ATS as they were on sale.
. After I had been there I noticed there was a pad missing so went back to see if it was there. He said it was missing when it came in . Didn't bother to tell me and raised the car on and odd lift with some strange metal blocks under the jacking points but I couldn't see the damaged side
Halfway through they came in the waiting room with some mythical tale of wheel alignment issues but wouldn't let me see it as public aren't allowed in the fitting area so I declined.
I've rang them but the staff who were on on Tuesday aren't in until tomorrow so I'm going to raise hell in there tomorrow
I'm getting the sill patched by coastal as I need the car tomorrow but then get my bodysuit to do a proper job and try and get ATS to pay which maybe a long shot
P...d me off that they come out with NAUGHTY WORD-NAUGHTY WORD-NAUGHTY WORD-NAUGHTY WORD- about wheel alignment issues that don't exist and if I wanted wheels swapped front to rear the existing ones have to be balanced but genuine issues like missing jacking pads are missing
