Left in the dark

I just recently signed up with supersonic for one of their LTE packages. Before taking this package, I was with the "blue" service provider. I cancelled my subscription with the "blue" service provider and switched over to Supersonic. But sadly I am coming to regret that decision. I've been without internet connection for 3 days now, and have been forced to resort to buying prepaid data packages, which are a lot more expensive than contract packages. I've been contacting Supersonic through their WhatsApp account, but all I get is the standard "F off" message "our support team is looking in to this". But I don't know whether that means this is a serious thing and I may need to find another plan or what? But I really had high hopes when I took up a package with supersonic, now I'm thinking, maybe the "blue" service provider wasn't all that bad, afterall, I've never not had internet for 3 days with them.
