No or intermittent internet

I called customer services on 3 Feb, speaking to Yolanda stating my dissatisfaction with the internet connection (or lack thereof) in our area, Ontdekkerspark, Florida. and was given reference No ***. On 5 Feb Emanuel called and requested I return his call. Left a message with Nomfando who was going to get him to call back. On Friday, somebody called my husband (I left his number as an alternate contact) and made arrangements that a technician would be meeting him at 16h00 on Monday 9 February 2015. Nobody arrived and noboddy called to explain why not. My husband has Vodacom data (NO PROBLEM) and I am getting very annoyed. Seems to me I need to change to Vodacom!
