I doubt you would be successful unless you have a close link to the BA marketers, in which case I guess you would not be asking this question. BA are a lot more hard nosed on this area compared to other Frequent Flyer programmes. Given what you say I'd hope you'd get to Silver fairly quickly, and if not maybe play the system a bit (e.g. Saturday night rules and Club Europe, going via Berlin or Helsinki, etc) to get there faster.

But there is a webform in the BA.com log in - just go to the bottom of the screen to the Help and Contacts section in black. Once sent you will get an automated response with a reference number, but it does not display a copy of what you wrote, so you best keep you own copy before you send it. If you don't have space you can put a summary in, then add details separately after getting the auto reply. Internally it works like an email, it may take a few weeks to be processed however.

I think direct email contact is a GGL and Premier perk.
