my accoynt gets suspend every week code E16-4

I got my dish installed on the 28th December 2015 and the installer told me to pay the amount of R320 which I dud the next day but not all the channels played for compact so I had to phone in and they corrected it, but since then every week the I get a notification that my account is suspended and I have to call the call centre for assistance using +- 50rand airtime everytime.. this morning again after paying R430 on the 28th of January 3016 my account is suspended again .... now how is this possible its very frustrating and it cost me alot to phone in everytime coz the self help service says that there's an error the account does not match with my I'd... for how long will this continue can't someone fix this problem for good or must I put the amount of airtime I use in my weekly budget under Dstv ... I'm very disappointed really its to much
