Unlock codes sent did not work

I was sent 3 unlock codes for my 3 devices.  The emails sent did not identify which device they were for.  I tried the 3 codes on my phone and they did not work,  I tried 2 more times and am locked out now.  I'm told I have to wait 48 to 72 hours to get new codes sent.  When I originally called, the emails were sent while I was still talking with Xfinity.  I am without a phone at this point and so disgusted that I want to leave them.  Customer service is the worst.
