Dstv walka 7' battery

<p>My walka's warranty has just expired and the battery requires replacement.</p> <p>I approached Dstv Umhlanga and was told to purchase a new walka as the battery isn't sold seperately.</p> <p>I paid around R900 for my walka and now i need to purchase another one at the price of R1600!</p> <p>I feel this is ridiculous considering the high monthly subscriptions i pay !</p> <p>I would like to know the reason for replacement batteries not being available and multichoice couldn't give me an answer.</p> <p>I would like them to replace my walka and add it to my existing decoders(2) insurance.</p>
