bad service and no feedback

I made payment on the 02/11/2015 and on the 07/11/2015 my services got disconnected when i called i was told that my payment didn't't come through and that i must email them proof of payment. i sent the proof on 09/11/2015 to their enquiries department and they gave me a case number. there was no feedback so i sent another one on the 12/11/2015 to their unallocated escalation and on the 13/11/2015 to their central finance escalation but with no luck of feedback nor my query being resolved. i was being charged a reconnection fee each and every week as they would disconnect my services and i would call so that they reconnect them while waiting for my problem to be solved. i kept calling and would hold the line for more than 30 minutes at times so airtime wasted as its not a toll free, until i got hold of the following people who asked me to send the proof to them and that they would help but til today nothing has happened nor any feedback given, Keitumetsi Mphuthi and Nthabiseng Sukazi on 01/12/2015 and 04/12/2015 respectively. i am still calling to date but not getting any help and they say i'm now owing R608.14 and i want it cleared. i don't know what to do anymore please help.
