Supersonic Fibre False Advertising

I am an existing Supersonic customer for two plus years and have had no problems previously with the Supersonic support / service! This however changed when I tried to change my current package to their 200 /200 Mbps Black Friday special for R499/month. I was subsequently informed by their sales team that this special is only for new subscribers, when questioned on why their terms and conditions don't mention this, I was told that if I'm not happy I should cancel my subscription! Well needless to say I have now cancelled and will be moving on to another service provider!!!
