Telkom charge me for failed debit order

I have been using the contact us link under my telkom profile since May 2015 to try and change my debit order details with nobody from Telkom getting back to me. I even made extra arrangement to make sure my telkom bill is paid this month and now Telkom comes and charge met R181 for a failed debit order. Telkom should pay me the R181 as I have contacted them twice via the contact us page and they not getting back to me and I paid my bill. So I would like this R181 to be credited to me.
