Grand Vitara suspension noise

You might remember my story about a noise coming from the front suspension of my 2010 Suzuki Grand Vitara. As you suggested I approached Suzuki in February this year and they agreed to pay for the parts, I just needed to pay for the labour. I have only just got around to calling them now to book the vehicle in as I have been quite busy with a newborn, and trying to get someone to look after the baby while I take the car down is hard. The dealer has now told me that the claim I put in was only valid for 30 days, however no one told me that, so I now have to fix this problem myself. I am now going to ring a mobile mechanic I know and ask him to come out and look at the problem and see if he is able to fix it. Is there anything more I can do?
