Fiasco

I was supprised to receive a pamphlet from the dealership that originaly supplied my car, quoting a separate service charge for the after market air con system that they had fitted. The cost for 'A' Service is £101.64 (1.3&5yrs) 'B' service £138.64 (2&4yrs). Has anyone else been quoted or charged for this? How do you guy's with factory fitted air con. fair with service charges.

I look forward to your comments with great interest.

Fiasco.
