following the conversation on the phone 2 days ago and my below e-mail, I still haven't received any update from you.
Here attached I resend you the copy of receipt of the fund transfer transfer I made in April for the first maintenance fee invoice, as per my last e-mail.
I will wait for you to correct the latest invoice before proceeding to the next payment.
I will not consider myself responsible for any late payment dependent on your lateness to correct the latest invoice
