Out of stock?????

<p>Sweet and short we upgraded out hd pvr to an explora on the R899 special what four months ago and is still having problems...ok so they said its the smart lnb giving problems,we phoned last week monday for a call out which costs R350 - R400. and they said its under warranty and dont have stock and is waiting on multichoice. When we phoned another accredited installer in our area they said that multichoice does have stock... henberg said that we are under warranty with them so we can only get it through them? is this true and why are we still waiting for a technician to come out?maybe multichoice is to blame? can someone please assist in this matter...we pay every month and cannot watch half the channels because of the poor quality on screen. we are really considering just cancelling everything at this point.</p>
