DSTV Multichoice are not honest

Why oh why is it so difficult to get reimbur*****t from DSTV Multichoice. They *******ly took R1178 out of my account on the 1st of July and now they say they are only willjng to pay me R878 back when the agreement was that they would only take R180? After being on the phone with their absolutely useless client service for more than 90 minutes over a few phonecalls, I am still none the wiser as to where my money is or why they took it! It has now been 14 days since they stole my money and I cannot get an honest answer. I have never dealt with such useless peopke in all my life.
