Thanks Guys.
What a weird story I have to tell...
Well went in Saturday and was met with a different chap than the person I'd spoke to before, he was insistent he couldn't do anything until Monday although the service lady said they could see if they could do a match there and then.
He said he has a box of the keys, he'll take a picture and see if there is a match...after he took the picture he then started spouting off about my brake discs, they're unsafe, you'll cause an accident etc which is one of the reasons I wanted to take the wheels off for and said I'll ring you back Monday.
I said I'm sorry but can you check so we can get the ball rolling or if you have a key, I'll buy 4 normal bolts off you now, without hesitation he said we don't have standard bolts in stock and you will be surprised at how many alloys wheels get stolen...(note here I live in one of the safest parts of the country, I don't know of anybody who has had anything nicked at all).
OK I'll go and have a look, 2 minutes later he came out with the exact key I needed and he was darn sure not going to sell me normal bolts, he said I'll ring you monday if I can order the key for you.
So he rings Monday and says can't order the key, a new set is £50 I then asked how much for normal bolts and he said £3 odd each and they have them in stock!!!
I asked him if he could tell me the dimensions of the discs on the car and he said the diameter of the discs are the same it's the widths that are different...I said there are 3 diameters listed for my model so I know there are different diameters, he said no, only the widths/thickness of the discs.
He made me speak to the service lady about the brakes, I explained very heavy corrosion with service area on the disc missing on a 28k car with scoring on one side and bad corrosion on the other and she outright said, well...I can tell you now the corrosion is lack of use and where you live, if you go for a long drive it'll clear up, without even seeing the car!
By this point I was losing the will to live and if I was not a nice person I'd have snapped but explained the car does around 30-40 miles a day usually a bit more. She finally agreed that a technician would look at it in 2 weeks time if we waited or 1 weeks time if it was dropped off (no offer of courtesy car) for them to check the calipers etc.
I just pray and hope that the technicians are better than their office staff. To be fair the service lady was nice but the parts guy had got to me first so put in a non pleasant mood so wasn't being very talkative by the time I got to talk to her.
ref the bolts, I'm going to tell them to replace for standard ones whilst they are checking out the brakes.
Just worried they're going to look at the brakes and refuse to let me have the car back before they put new discs and pads on.
