Hi,
I had a contract with the number XXXX.
I've been charged by mistake of 42,89 EUR, and it has been issued a credit for that amount last August.
I still monthly receive the invoice with this credit, but I don’t only receive any bank transfer about it and I cannot even access to my account because it has been deleted a few months after the contract was over.
I tried to contact the customer center via chat but I cannot use the proper one because it requires a login with a proper account, not this community account that I just created now.
I don’t have time and language skills enough to call the call center and try to explain what happenned.
Who can help me?
