Super ****ty service

I have received such bad service for the past few weeks just to cancel my application with this company. Each agent advise the same feedback. I have been sitting with the problem for more then month now. I have been struggling to get fibre for the past 4 months because something was blocking my address only to find out that it was SUPERSONIC and I have contacted them to find out if there is a record of my address on their system and that agent has advised that there is nothing only to find out now a month ago that it is them blocking my name. Now they not even able to release my line. Super tired of calling everyday after this people and nothing is getting resolved.
