Failure to provide an installation, even though it was promised within 14 working days

I have been with Supersonic years ago, for several years. Due to financial struggles, I opted to go to a different service provider, whom was able to give a better package, for a better price, after Supersonic refused to assist. I have since relocated and have opted to give Supersonic the benefit of the doubt and app**** to have a service installed from them, however, more than three weeks (more than 14 working days), has now come and gone, which is their promised lead times, however I am yet to have an installation or an active service. I am of the intention to take the matter to the obmudsman as well.
