Repeatedly Promoting deals with no stock

I downgraded from a 10meg to 4meg uncapped online deal after seeing the December advert. I have not received a LIT box or modem to date. My new bill does not even reflect the Lit box, however I see a new January advert promoting the LIT box, modem and range extender. Calling the service centre is painful.(long waiting times, slow computer excuses, abrupt ending of calls whilst on hold, no call backs or follow ups, being passed from one call centre agent to another, call again and repeat...) After enduring the long ines at the telkom store, they state that they cannot assist with online orders. I was informed to call the call centre for assistance. The saddest part of this experience is that I have been paying for the 10 meg capped line for several years on a month to month contract at a substanially higher rate, however my download and upload speeds are the same after downgrading to a 4meg line.
