P*ssed off

I bought a new explora from (On Air) last year that I wanted to register under my name coz all along we've been using the explora that was registered under my late wife's account, the technician came to my house for installation but somehow there was a misunderstanding between the technician and the call center agent, my new decoder was registered under my late wife's name instead of my name, when I realized their mistake I let them know and told the agent to rectify it, however she told me that she can't change it coz it's already in the system, she said the only thing I can do is to do a change of ownership, after that I did my research and found out that I cannot do a change of ownership bcoz the decoder is a contract decoder, meaning until I finish paying for the decoder I cannot change the ownership, what makes me angry is that the mistake was not made by me, but I'm the one who's suffering the consequences, now in order to watch TV I have to pay R1400 whereas I'm subscribed to compact+, I have to pay for another decoder that's still in my late wife's name, I'm tired of paying that much money, I've paying it since November, if something can be done about this issue please help me asap before I look for other means to watch TV, coz I can't go out and buy another decoder while I'm still paying for this one
