oh.. that one.. i never got problems with billing 
anyway, i had problems with something of that nature when Starhub
(then SCV) blew up the Nicam card on my tv...
in the beginning, we actually paid Sony to come fix it because we
didn't know what happened.. they replaced the card and 2 weeks
later, it was a mess again.. this time, we dug it out from the
technician that they were replacing these cards everywhere.. he
thought it was SCV...
i dragged SCV down and demanded that they foot the bill since Sony
said it was their signal blowing up the card..
they started to argue, i told them that they settle it and fix the
card else they're both going to get it from me...
the card was fixed and i think SCV changed their signal thingy
after way too many complaints from the customers..
