Colissimo - Shipping between grams brackets to a country

Hello Zar,

I try to have documentation with the french poste about So Colissimo. But no answer from us. (multiple calls / emails / La Poste Rendez-Vous ...)
Tired to deal with this company.

OK, thanks for your answer.

I'm getting the same errors when trying to add this pulgin. Is there any more detailed documentation?
