100% agree, expect a standard copy paste answer from FB. But I must also say that I wrote an email to the General Management or Air France directly (Directrice Générale) and her assistant called my back and I had a very good and constructive conversation, they were fully aware of "our" (Frequent Flyer with high status) "problems". She ensure me that they were working on a solution and that the situation was evolving the whole time. A few weeks later they came out with the rule of re-crediting the overflow from the year before.
