Hey Twitter Support! As mentioned in our email to you from wpcapetown@gmail.com, this page indicates the subject and reference number for the open support issue we have with regards to the @WPCapeTown Twitter account being locked:
Case# 91633762: Appealing a locked account – @WPCapeTown [ ref:_00DA0K0A8._5004A1TWpVr:ref ]
I hope this is enough proof that we do own this domain for you to unlock the account for us.
Thanks!
