Annoyed customer

I have bought an explora price lock for R119 in February with installation. I struggled for more than a week to get a dstv installer to come install my explora... finally they came and install on the 28 February and dstv said i must call them once it has been installed so that it can be activated, i then called on the 28th to tell them know.

Today when i wake up they have disconnected my services because they said that i didnt pay the R119 for February.... My question to them is how do i pay for something that hasn't been installed? I dont understand why i must pay R119 for the month of February but i didnt use the decoder at all in the month of Feb.

Please assist because am tired to call multichoice every week about this.
