Poor service and False advertising

I have app**** around the 26th or 27th August for the R299 10G + *10G Hauwei WiFi special they are currently running. I was told they don't have any stock available but they are expecting delivery around the following week Wed or Thurs and they (Musa) will give me a call once stock has arrived. Up to today 17/09/2015 I have not received any call from them I have been doing the calling with no Joy. When I called last week and spoke to Salome I asked her if I can go to Greenstone and check if they have stock and if they have can they give me the WiFi Router and she said yes she will ask Musa to upload my application - I went to Greenstone yesterday and was told that is not possible I need to do a new application and there cannot call Sandton as their phone is never answered. This is pathetic service - It would have been nice if they called me and advised that they still don't have stock or even return my documents if they cannot meet my request! Why advertise something you don't have - I could have gone to a different service provider who probably have stock available
