Cancellation of email address

Good day,<br> My family and I have used [Email Removed] for nearly ten years. As from 16June, it's no longer valid. We have tried to phone the call centres etc but no one could help. The error message is invalid domain. <br> This email addie was connected to an ADSL line that was cancelled. Maybe Telkom also cancelled our usage of this addie. But..we do have another Telkom account so we are still customers of Telkom. We use this email addie for all our family business and quite a clients have complained because they cannot get through to us.<br> <br> Please help.<br> <br> Yours truly,<br> Melanie Baker
