Have you not had two years of breakdown cover?I am sure you are correct. How does that compare With the £600 Inhave paid the RAC in the last two years and had nothing?
It does seem like a trivial item it’s like judging whether to claim on the house insurance for something
I’m not sure what terms of RAC cover are, but many ‘breakdown’ policies exclude items such as bulbs. If your policy doesn’t include such repairs and you’re so concerned you could ask your local garage to attend and repair.
