Furious!!!

I asked Metrofibre and Supersonic to cancel my subscription with immediate effect and they have been dragging, however I still don’t have internet connection(they are not providing me with the service I signed up for). I reported that I had no internet connection with Supersonic on Saturday and they kept saying I should reconfigure the router and on Sunday they logged a ticket with Metrofibre and Metrofibre didn’t bother to assist and they told me to wait as it’s gonna take 3-4 working days mind you I had already spent 48 hours with no internet and consultants from Metrofibre didn’t care at all about my time and all. They kept on telling me I should speak with Supersonic and I asked both companies to release my address so I can move to another provider who’s reliable and they didn’t. I have spent over R300 buying data as I needed internet connection to work. I asked them to release my address still nothing and Supersonic asked us to wait for Metrofibre and Metrofibre consultant are not helping at all. I just want to cancel my subscription with immediate effect so I can sign up with another provider since you are not providing the service that I need. It’s so frustrating and this is very poor customer service! CAN SOMEONE PLEASE HELP!
