Payment Reversal - No Way to Contact Telkom

I am a Telkom LTE customer and i am happy with my LTE at the moment. I had problems with my Bank accounts and my debit order didn't go through for my LTE to which i made a manual payment to Telkom which didn't debit my account and the next month i had double payment which went through. On further investigation I saw the payment was made to my ADSL line which was cancelled years ago. How do i get a refund from Telkom? Please assist as the call centre route is not working and no way to get to Accounts Department.
