Dstv problem

Today I received a horrible service, I went to spar waterkloof to pay for my dstv and the lady indicated I must pay R917. 00 and I said to her make it R920, which she did. When I got home I could not clear the E16 - 4message, I called the call centre around 19:00 and spoke to Nokulunga asking her to help clear the error, after trying with no luck she tells me there is R59 outstanding on my account, I tell her but it's impossible because I got that amount from the shop, she tells me I didn't get the amount from Multichoice therefore they can't help me, I therefore ask to speak to someone higher than her, I guess she just put that phone aside till I dropped.tonight I will suffer the pain of not having a dstv. I paid the money to receive a bad service..
