Hi @Z.Ivanov ,
welcome to our community.
When you paid twice there is a credit, which covers your next invoice if the credit is sufficient.
Alternatively we can transfer you the credit back, but the whole process takes 1-2 weeks, so the coverage for the next invoice is the much simpler option
Best regards,
Michi
Hello,
Thank you for your response.
On 06.05.2020 there is a new payment for the last O2 invoice for 36.09€. So it seems that it is more reasonable to return the mistaken second payment on 04.05.2020 /51.97€/, even if it takes 1-2 weeks to do so.
Please confirm it. Thank you for understanding!
Hi @Z.Ivanov,
thanks for your message.
Yes, I see that you have now a credit of 51,97 € on your account.
According to your wish, I will now order the transfer to your bank account. This will take up to 2 weeks.
I hope you agree to this solution.
Loving greetings,
Tobias
