Hyundai i10 second year service

It's fast approaching the time for my Hyundai i10's second year service, my doesn't time fly. I have to do this in order to maintain the 5-year warranty and as such I think it best to have it done at a registered Hyundai garage to avoid any "But you didn't have it serviced at a... " wriggles. My first year service cost around £150, my second year's £300... say what?

Time to shop around, so I contacted another local garage or at least tried to. I've rung and had someone promise to get back to me. They've then tried to call me at home despite me giving them my mobile number (I'm already in their database). I've called them back and left a message. I've called them back again to find they'd left. I called again this morning and was put through to an answering machine again. Then lo and behold a call on my mobile, they'd tried my home number again and this time had the sense to try the number I gave them to call.

Oh they didn't have that information to hand, but they'd get it for me, was this the best number to contact me on? Yes, yes it is [sigh].

[Update - tried a third garage and got a price straight back. Not much different to the first one though he did go into more detail as to why it was more expensive this being a major service rather than a minor one]

[Update - second garage, even more expensive]
