BIGGEST MISTAKE EVER, THANK GOD FOR WIFI!!!!

I had DSTV 3-4 YEARS ago on prepaid basis (Month-Month) So when I do not pay Multichoice would suspend me account until payment is received again. So when we moved houses In the new place we went with Wifi Netflix ect. I sent through a cancellation letter to Multichoice eventhough not necessary as I was on month to month basis only to find out they have handed me over for outstanding payments, What FLIPPEN PAYMENT I would like to know!!!!!! I have this company calling me on my WORK Phone this last week everyday, for what reason. Please sort this out ASAP. Call me on ***
