Rejection fee because they told me to reverse the debt order

Telkom can expect a cancellation Request from me today. after i paid my bill on the 25th by EFT last month they debt my account on the 31st of January 2018 for the same amount. i Called the call center to refund my money and the consultant told me the debt order doesn't reflect yet but the ETF payment does. The consultant told me she can only refund once its reflecting after 72 Working hours that is like 5 days or i can reverse it at the bank. after i took her advise and reversed the debt i now received a invoice with a rejection fee of R200.94 . Telkom is robbing they clients if this is how they do business, they will never get another cent from my account.
