Won't return my deposit even after cancelling line

I've had a Telkom line for many years, and a few years ago i was interested in applying for a Telkom ADSL line. <br> <br> I was approved for this service, however i had to pay a R700 deposit which i was told i will get back after cancelling the ADSL line. all fine and well, kindly note that i CHOSE to have Telkom as my line provider at the time and therefore paid the R700.<br> <br> Fast forward a few years and after absolutely atrocious service from Hellkom, i decide to move my ADSL to a more competent service provider. Now they tell me that I can only get my R700 back once I've cancelled my entire line with them. <br> <br> So they would rather lose all the business i throw their way every month just so that they don't have to return my R700? Am I earning interest on the money that you're holding?<br> <br> Really Telkom? Can you really afford that? And now this woman I have been speaking to is being really passive-aggressive and I've been put on hold for the past 15 minutes. Even this complaint will receive a half-assed response about 3 months from now. <br> <br> Keep on going, jobs are scarce and one day soon even Telkom will become redundant.<br>
