Bad servise

I phone dstv just now in connection with my account. My decoder went faulty yesterday and this morning I wanted to stop my dstv account until I get my decoder from repairs as I was informed my decoder can take up to 21 days for repairs.I was told my account will only be stopped as from the 01/04/2018. that means I am paying for a whole month without watching dstv. I feel dstv is robbing it's clients like this.
