O2 prepaid M

Hello,

I bought the o2 prepaid M with 15gb. Last month the plan was working well, but today somehow O2 didn’t debit the money in my account, I receive a message asking to recharge that the plan would be automatically renewed.

i did that but the plan wasn’t, it automatically charged me 1 euros for a basic internet daily plan and now the offer with 15gb is no longer available there and I don’t know how to recovery my plan
