Cancelling contract not possible

I want to cancel my subscription to DSTV. <br> Their system won't allow them to cancel today. I have to either pay for another month and cancel it then on or before the 2nd; or not pay immediately and wait for my account to disconnect due to non-payment but then have to pay for the 5 or 6 days it took for the system to disconnect - which will then cost me according to the system R110 (or R17 per day - which according to my calculations is R96 not R110).<br> This grace period before they disconnect is for people who can't pay on time. I phoned them a day late to cancel but now have to pay for 6 days of being connected. No grace period for that???<br> I don't know how they get to R110. I don't know how they cannot cancel my account if I phone them to cancel it and give me a pro-rata amount. Been having a lot of problems with them lately. Not a happy customer. <br>
