R800 payment + R349 credit JUST disappeared????

I have been on the phone for hours in the last 2 weeks to try & resolve this problem - and once again my service got disconnected for the 2nd time!<br> I have paid my account (as always) on the 26th of December 2016. The transaction went through successfully. On 2 Jan '16@ 1:19pm I received a sms from DSTV stating that my account is overdue and will be suspended if I don't pay R710.48. I was on leave & was in no mood for fighting, so I have paid another R800 into MNET's account on 2 Jan 2016. On Dec invoice it shows that I have had R349.52 credit on my acc. All together I'm suppose to have R1949.52 credit. <br> On 12 Jan my MNET service got disconnected. When I phoned the call centre, the lady checked their system & I was told that the payments never got allocated to my acc & that she will do so and reconnect my service. Proof of the 2 payments was sent through. My acc still shows I owe R808, I was also charged for the re-connection fee & yesterday whilst watching the cricket, my Walka 7 service got scrambled for now reason whatsoever. Where is my R800 paid on 2 Jan & the R349 credit I had???? I spoke to 4 consultants & still NOTHING happened!! WHAT MORE CAN I DO TO GET THIS RESOLVED???
