Bad Service on my account

I am struggling to get my dstv account sorted out, it showed I was R990 behind, I paid R1000 send proof to connect, (My refference was wrong) So i needed to send the proof... When I signed in, it showed I must by again R220 to active the account, I paid it as well... I phoned seven times R200 airtime to sort out them to connect me... They activated the wrong decoders and now I need to pay almost R2500 again on the 25/05 and For WHAT i dont know.... Never struggled like this...... My Explorer and My PVR is the only ones we use the last 5years or so.... The pvr is not active and the Explorar keep throwing out a message for not paying...... Please I cant get a hold of agent, and it cant be that amount.... Regards Zelri ***
