Bad Telkom product (Aztech 700WR-3G router)

I am on an ADSL contract with Telkom and has been using their own router (Aztech 700WR-3G) for almost 2 years now. About 2 weeks ago, I started experiencing frequent problems of no internet connection and the only resolve is a "hard reset" with associated re-configuration every single time. This temporary "solution" unfortunately has now stopped working! Since yesterday, the problem repeats itself within a few minutes after the reset. On further investigation, I noticed that Telkom has a nationwide problem with these Aztech routers, but they are unwilling to admit it. This morning after numerous fault logging I went to Telkom (Centurion mall) just to find 7 other unhappy customers with exactly the same problem. Still Telkom refuses to admit that these routers are a problem and they are not interested in replacing them either. While at Telkom, I also received a call from Telkom stating that I should phone ********** 268 as they can help me with a firmware update. Unfortunately, there is no such help from this number and I was told that the technicians are working on this (now apparently known problem with Aztech?) and that I should WAIT, of course, with no commitment from Telkom to be resolved anytime soon.
