SLOW, VERY SLOW UPLOAD AND QUESTIONABLE DOWNLOAD SPEED

Ok, here goes. After receiving a number of very friendly phone calls from a lady by the name of Megan, my wife and I decided to sign up for the Rain R479 package (the unlimited, uncapped, un-everything package). We paid the R479 and yesterday (Tuesday) we received our sim. Within a short while I received an SMS stating that the sim was activated. Thus far, fantastic service. Well then things started going south... Putting the sim into my router, one that I had been using with my soon to be cancelled Vodacom sim, I decided to first check the speed. Download came in at around 7 or 8 mps - not bad...But then the upload speed barely lifted the dial and came in at around 0.4 - 0.6 mps. Nah, this is simply no good!!! Just to check a few things I tried the downloads, and well... Not so fantastic as it takes around 30min to download a small video file... So I logged on to the Rain site (using the login that Megan had sorted out for me) and looked through everything there, including the 'Optimise Signal' part. Nothing!!! Next I sent a message to support, and then another one... I also sent a number of emails to Megan - seems that now that she has made her sale she ignores my mails. Question, did I make the worlds biggest mistake??? Am I going to cancel my subscription by March end??? I have to wonder now if someone, someone, will get back to me from this review. Yes, the initial service (while trying to convince me to sign up) was fantastic. Yes, I received my sim VERY quickly. Yes my sim got activated quickly. But...BANG that's it, no support thereafter. Will I cancel my package - that is purely up to Rain themselves...
