Confused and sad client

I’m a debit order client of DSTV Multichoice and my debit orders are scheduled for the 22nd of each month. My last debit order was December on the 21st, then the next one is suppose to be on the 22nd of January. But to my surprise, my package was suspended because of payment. The breakdown of the payment is the subscription fee and reconnection fee. How do I get disconnected whereas I’m a debit order client and the debit order already went through on my agreed date. So I’m expected to make payment today and still get debited on the 22nd again. I called for clarity but the consultant couldn’t assist.
