Unfortunately I got suspended by Twitter for using many hashtags in a series of tweets (I was watching Eurovision Song Contest so I was usingf the official hashtags). I could have unblocked the account easily and quickly just by inserting a verification code that Twitter should have sent me via text. Same thing happened to my husband in the same minutes, he got his text, entered the code and got back his account right away. But in my case something strange happened: Twitter could not complete my request due to some technical problem and I didn't get the text message. Try again later, it said. But after that, everytime I tried I got the same error message. And if I tried too many times I got a message saying I made too many attempts. So now I can't unblock my account if I don't get this text! My phone number is correctly registered on my account. What can I do? It's like a glitch that got my account or my phone number "stuck" somewhere. I submitted a ticket for support but haven't gotten an answer yet, and I doubt I ever will, sadly. I had my account for ten year! Thank you so much for any help you can give me.
