I paid 2 times a same month

Welcome @Patrick barri. You should't pay the same month twice. Is it about your mobile subscription? 

Please fill out this list with at least your mobile number, postal code and number, date of birth and the last 4 digits of the bank account you pay your subscription with. When you're done, write another message over here. Then I'll take a look! 

I assume you don't have any questions anymore since I haven't heard from you anymore. If you do, please let me know.
