Supersonic - grossly *********** service delivery!!

Today is the THIRD time that Supersonic has cut my internet service, leaving me and family members within household hugely inconvenienced during work from home hours in particular! I have to use my airtime calling the "customer service centre" who continuously transfers me from one department to another and no one bothers to return my calls, after I hang up when I can no longer hold for over an hour. I resorted to opting to holding on during all calls, instead of taking up their offer to call me back, since they never called me back last week, all the while my personal airtime was being used.No one can tell me why this problem is recurring yet Supersonic happily accepts my punctual payment every month. All I get told is that my matter has been assigned to a Project Manager - I am convinced these PMs are phantoms, I do not believe they exist at all! Just last week, during the second incident, my internet was cut during working hours and the most infuriating part is that NO ONE seems to know why this keeps recurring. The only thing I did was to move house nearly 6 months ago...and Supersonic's system keeps mixing up the old and new line, and they try to feed me some hogwash about the incorrect triple P line / log in credentials being in use on their side - neither of which is my problem - so they proceed to terminate the incorrect line...THREE times!!!! I am so livid and have had it with this non Service Provider. I am a customer whose account is continuously in excellent standing however it appears Supersonic has no regard for this fact and client retention and satisfaction clearly do not seem to be a priority. The line used by their agents when taking calls, "How can I brighten your day?", is a huge joke!! Supersonic has failed dismally, in my books, to say the very least!! I will never recommend them to anyone, ever!!!
