Payment arrangement

I ran into arrears last year on my pricelock plan. ever since I have made arrangements to pay it off, but DSTV either tried to deduct the enire amount and not the arranged amount, thus there wasn't funds to pay such big debit orders. since December I have tried a number of times to re arrange a payment plan, but everytime I get disconnected after a few days. Today the same, every couple of days I get disconnected in spite of paying what I arranged. The last arrangement's call reference was ********** . I arranged to pay R1000 extra , and in December I actually payed R2500, then 2x payments in January to help cover the arrears. Now I'm told they wont reconnect me unless I pay the full R7000 odd arrears,, I have spend almost R2000 in phone calls alone to try and resolve this .........
