Bad Service

i bought DSTV on the 31st January 2015 and it was installed same day, my installment is R295 Plus pro rata which was R19.67 so on the 2nd of Feb i paid R315 the money that i was told to pay, i watched in on the 31st of Jan until the 2nd of Feb, on the 3rd it started to give me problems i then decided to call their call centre to find out what was happening because i have already paid the money that is when i was told that i was charged twice for what i dont know they apologize and everything went well that night, until the following morning when i switch on my TV the was a message saying that my account was suspended but i couldn't understand why, i called the call centre for the second time they apologize again and i was back on, until the following morning again this thing as been happening everyday for the passed two weeks now, im so frustrated i dont even know what to do anymore , for a first time customer i should be happy but i'm not its hardly 1month
