Not Receiving Twitter Verification Codes

So I was locked out of my Twitter account, and I’m on the page where it says they’ll send a verification code to my phone via SMS. I’ve tried this probably 40-50 times over the past 3 days, and I haven’t gotten anywhere. I’ve filed numerous help requests with Twitter Help and have gotten no help. I’m getting to the end of my rope with Twitter Has anyone else ever dealt with this/know how to resolve it? Thanks!!!
