call centre staff with no experience

I reported a fault to the Data Support line 155, which tells me someone needs to be competent enough to handle all the queries if they working in that department. I am running errors on every site, every page, as well as my gaming site, which points to a common fault. I have purchased a brand new TP LINK modem which was setup 2 weeks ago, and went through the process of rebooting both pc and modem, checking the router, and obtaining a new wireless connection PRIOR to contacting Vodacom. I was asked to go and check everything I had already done, then told if their was no change within 24 hours I must phone again. What a joke, seriously, this is the service I get, and what exactly is going to change? Its a freaking Vodacom fault, possibly running errors from the tower on the Telkom DSL unit, but its not on my PC or Modem. Please have the decency to have a technical person answer you're calls so we on the same page immediately instead of wasting my time.
