Complaint case closed as unavailable - need written support

I have already contacted TELUS Customer Care multiple times and a formal complaint case was opened. After two unsuccessful callback connections, I was notified today that TELUS is closing my case because I was “unavailable” and that I must call Customer Care again.

I do not accept the closure and do not want to restart the entire process by phone. I also tried the Management Team complaint page, but the Home Services link only reloads the same page.

Could TELUS_Support please contact me by private message so I can provide my case number and account details and resolve the cancellation in writing?
