No response from tickets in more than 10 days

I have send multiple tickets from my main email account and this account, about the error message i get when i try to set up my previous authenticator with my serial number/restauration code, i get the message : “Error… An unexpected error occurred. Please try again later.” I have looked up online and did all the troubleshoot asked, clear cache of the application, look for enough space on device, etc. And finally people online say that you need to remove and put it back for it to work .I just want to point out that this is probably the 15th ticket response that I have received in that case asking for info’s, IDs, Canadian ID form, etc. Which I have give every time. And it take around 24 hours in between each of them to received a new email asking for a new thing, which the one of the last was that I needed to use the live chat… which is disabled. And now, blizzard is just not answering anymore to my tickets on both account. for more than 10 days. I feel like I am left on my own with no help at all and find this experience extremely unpleasant and shouldn’t happen to a 20years customer, what is happening now if i get no response?. I hope to get a response really soon. Thank you
