Telkom
Debit order submitted 2 days prior to due date

I have instated a debit order paying my Telkom bill on the 25th of each month through Nedbank as this is the date my salary gets paid into my account. This month Telkom put the debit order
through on the 23rd. It was rejected by Nedbank as unpaid and the bank charges me
a R 90.00 fee. I have logged a complaint at Telkom. A lady returned my call two days later
who told me that it is the banks fault and i must tell them to reverse the amount. I have contacted
the banks call centre who told me that it is not their fault but Telkom. I again contacted Telkom
but to no avail. They blame the bank and the bank blame them. Who is responsible to refund my R90.00?
