Bill me for there fault

<p>7 months ago i had DSTV at my house before i moved to a new place with my wife who had her own DSTV. As i do not work in SA i am only at home every 6 weeks I use to go pay at a Spar or Checkers and switched it on and normaly when it swiches off is when i leave again . Use to work great as i did not see the need to sign up for a debit order cause then i would pay for DSTV and not watch it for 6 months in the year . Hope this makes sence . So 7 months ago i moved in to a new house with my wife and we decide to keep her DSTV as it was allready installed in the new house . Now out of the blue after 7 months i get a SMS from DSTV that i owe them R417.90 because they forgot ton switch it off for 15 days or something ?? How is this my problem as i always payed to get it switched on when i am at home ? They even phoned me and asked me if i want to upgrade or cancel and i told them i am cancelling cause my wife has got DSTV allready . Best of all is they send you a SMS saying you will get blacklisted or you should phone this number ********** 042 which no one answers ever or they just drop the call directly afer they pick it up ? Really unexeptable as this was like a pay as you go tipe of contract and its not like i cancelled a debit order </p>
