False advertising.Paid & service not activated

I'm using an Explora compact & I received a discount voucher of R250 through an sms from DSTV Multichoice & I was told to pay R62,91 to get my service activated so I paid & Immediately after paying I checked my balance & it said I owe R286 & my service cant be activated untill I pay the R286.This is very ridiculous & its actually False advertising.Can the Government please intervene.This happened in March & some agent tried to explain and she did not make any sense.The was a time i had to pay almost R600 for my compact no managed to explain why so much.Where do we report false advertising.I am really disappointed since I'm a loyal customer of dstv.Does anyone know a better service provider.If my dstv is not activated I'm taking to radio and social media.Im a journalist so this would be very easier for me.We need to expose false advertising its really wrong.DSTV will loose lots of customers if they go on like this.They cant even reset your decoder when you get no signal on the wizard installation steps.This has nothing to with bad weather because its not even rain or windy.The agents are programmed to say call the installer as if its free.Dstv need to pull up their socks.Many people are having the same problem on Google.
