Appalling Customer Service

I have never seen such *********** and appalling service. I called in December around the 15th to update my bank details for my monthly debit order. I was advised that it was done...knowing that it will be effective from the January debit order. I called again in January just before the debit order date to check if indeed my details had been updated and I was assured that was the case. Bear in mind that getting through to a Telkom call center is not easy. Having noticed that neither January nor February payments have been deducted, I called again only, to find out that my details were not updated. What is going on over there?!!!! In addition to this, I have incurred charges for rejected payments yet Telkom is debiting their payments because of their incompetency . I have since called to speak to a manger, my call was placed on hold for about 29 minutes and then the consultant hung up. I am disappointed in their customer service and won't recommend it to anyone. Definitely going to cancel my account which I believe will be another lengthy and tedious process.
