Supersonic-WORST SERVICE

I have been without internet for 45 days. Fibre line was in my dads name and he passed away. Was told I had to apply for a new account. Then I was told I had to cancel. Then I was told that I don’t have to cancel I have to do a change of ownership. I was told I was active by one department and then told I was not by another department. I NEED internet!!! I am so frustrated and feeling completely hopeless because I don’t know what to do and supersonic is not coming through for me. R2000 on data and 200 minutes of airtime gone and still NOTHING.
