Telkom collections department worst SLA

The billing Department is the worst department at Telkom. They can never answer a query. They keep pushing it on the collections department. Telkom if a debit order is missed and paid again after 2 days why are we charged so much fees? And for debit order not authorised and not on my debit date set they dont want to pay my banks penalty fee. Do you think we all have money sitting in our bank accounts all the time??????? Then on top of it we must wait 14 working days for it to reflect and on top of that we still get double debit agh man worst experience. This is the 3rd time now! I ask to speak to the manager they dont want to allow that as well or no manager calls back. And if we give low rating at the end of the call the system says its not recognised. What a joke really. SLA's need to be worked on! It will be a solution to many problems
