Misterioso I do hope you soon get that sorted. it's such an unsettling situation to be in, but as you say, at least the bank spotted it.
I have a moan about my bank; Our local branch is closed for "rennovation" which I suspect means "automisation" and even less personal service. We have been invited for several months to use the nearest branches - all of which are between a 20 to 40 minute drive away. I managed it once only to find myself having to queue for ages as this branch was now dealing with more people. They were also being "renovated" and were working in a sort of temporary hut!
Needless to say the renovations are all taking longer than estimated; I have been trying to pay in this term's cheques for a month but have never managed to get to any of the branches available. I have also found that the new little "bordereaux" we have to fill in when paying in cheques now has space for only 4 instead of 8 cheques and requires several new bits of information which of course have to written out twice as many times as you can only do half as many cheques on one bordereau.
I suspect this is to move us all to using computers and smartphones to do all our banking. So far this hasn't taken on in France as there are still to many zones not covered by internet; Even near where I live there are some areas in the foothills of the Pyrenees where reception is unreliable. What a nice world it will be when we all do our shopping in automated shops and are banking in automated banks and have our medical consultations on line etc. There won't be any point in being human any more. Aaaaagghh!
