Debt collecting for multichoice

A third review in less than a year for service that sucks. I joined the queue at 11am and left at 14:20 without a solution. I went to change ownership with signed documents but i was not assisted because the previous owner of the decoder owes multichoice R204. Now I'm supposed to do debt collection on behalf of multichoice otherwise the decoder won't be transferred to my account. I'm stuck between multichoice and their former client. I wasted 3 hours queueing first in the parking lot, then inside the mall and finally inside the store just to be told nonsense. Nowhere in the change of ownership forms does it mention settling the previous owner's account Cust no. ***9
