BMW cant get parts for my car

[lee]

Hi All my car went into elms in Feb running very ruff i get a call from Emma the next day letting me know the head gasket has gone but it has also warped the head and block but new engine all be covered on the warranty.
Happy days get the car back 4 weeks later but 400 miles later the new oil pump packs up taking the rockers out and scoring the cams.Cars back with elms they are more than happy to do the work to put car right but BMW dont have the cams in stock and cant get any more as the manufacturer has now gone bust.I have lodged a complaint with customer service but they tel me im looking at 2-4 months untel they can get some cams made for me.
So its looking like i will have to pull out of the trip and will not have the car for the hole summer as you can imagine im very upset about this and just dont know what to do now.
