Pathetic Service

At this moment I am ****ed off , I was trying to tolerate your bad networks on weekends but now Im fed up, I have been trying to update new banking details on the 20th June and your system failed to update my banking details I tried to do this 3 times But instead it changed my debit order date. So my debit order went off on the 24 June so i assumed it failed to update only to find out it debited again on the 1st of July . I called they c\c and they Team leader Carla something stated he cant refund me because I changed my debit date , So when i asked why did they debit then on the 24th June, he stated I am a Postpaid client which I dont understand.. And then he hanged up on me, What customer service is this. There is no accountability whatsoever. Im never using this network! You dont call back your customers.
