Account not deactivated

On 17 July 2015 my telkom line and adsl ( data and line) should have been closed. The line was deactivated but on the site one of the services still says executing. Im getting billed now for a line that i cant use and supposed to be closed. I left 3 complaints on the the telkom website but no response in the last 3 weeks. Phoning doesnt help, as you wait more than 30 min .<br> Original *** for closing of account
