Rain is a massive issue!!

What a waste of money! I recently purchased the R479 unlimited 4G sim from Rain. Firstly, the delivery was supposed to arrive on Monday and only received it after many calls to RAM. Once received and waiting for sim to be activated, I placed the sim into a hwawei mobile wifi device (after being told it would work on any 4G device) I followed the installation process. Nothing! Called the help desk and was told I would receive an email and must follow the instructions. Stoll waiting for the email. Took the sim, mobile wifi device, phone and laptop down to Glenvale computers to ask for help. Was told by them that I need a new router at R1899, as they had a lady in yesterday morning with the exact same device and problem. I have now had 5 days of no connection, and have paid! Next step is consumer council or a full, immediate refund! I am not waiting months for my money, as has happened with so many other people.
