Bad attitude and overcharged

i pay my account on the 27th of each month , however for the last 3/4 months DSTV has been disconnecting my services and i always need to pay in and pay a R50 reconnection fee. I never queried it up until Saturday 25 July 2015 at 8am. I spoke to a lady called Mashaite molele who advised me the i must pay in R680 which includes R50 reconnection fee. I then discovered that when I called in in April to advise that my decoded was struck by lightning the had been charging me for two decoders and I only have 1! I called them and initially asked them to pair my smart card to another decoder which my sister has given me but they told me that your smartcard is linked to my decoder so I will have to purchase another one. Which I did cos my old smartcard and Lightning damaged decoder. called to activate my new one and again advised that that my old one was lightning damaged they assisted me a was very friendly!!! Now to MY SHOCKING SURPISE I AGAIN AM SITTING WITH HAVING TO PAY THEM 680 and I am on compact which is R319. Stop ripping me off !! CPA\ means the Consumer Protection Act
