No Feedback no confirmation of process

I sent an email to ********** to request a settlement amount on my Game and Makro account, There settlement letter does not specify how to confirm closure of these accounts once paid. I paid 04.09.2017 which was in their specified 5 day period. I have sent proof of payment back to ********** and have been sending them emails to confirm settlement and closures of these accounts and to date have received no feedback if these accounts have been closed. I refuse to incur any further charges on these accounts I want proof that they are closed.
