Ticket forcibly even though nothing was solved

I have been having lag issues with overwatch so i contacted support as there was nothing on the internet regarding my weird lagging out.
the support was horrible as they would reply with a generic copy pasted reply that had nothing to do with my problem, they would just ignore things i had said and say restart your router or check with your isp even though i told them that i did do this and this was not the issue. After about a week of back and forth with them asking for the same system files (that i provivded) 4 seperate times, they just say that my ticket is answered and closed it.
My ticket does not exist anymore, it’s not even in archived tickets.
