Cant log InError51900314

I have been trying to play all day I keep getting the same error message Error51900314 I looked at all the forums, tried all the resets, the cache renaming, stuff I don’t even understand, my internet is fine I can play any other game and any other system, before it would pop this message up a couple times and then log me in, now it wont log me in at all, I tried contacting support but when I write the ticket I cant click on submit and its asking me for things I have no idea about because I am not an expert in computer, and of course I just find out there is no way to contact blizzard by phone which I find ridiculous. Anyone that has encounter this issue found a solution? Or is it time to quit again, I honestly thought they had gotten better.
