How can I cancel my subscription??

I did cancel my auto renewal but it continued anyway! 
I hate this service now and want out ! 
its typical though with auto renewal! You’re told you can cancel at any point but when you try you never can do 

I can’t even find which 1 I have atm . It’s early in the morning so I’ll try finding it later 

I think after all these years of paying a ridiculous amount for Trend it's time to say goodbye!!

im so sick of trend turning off or turning off parts of my defender as well as messing with my own wifi ! 
ive put up with it since the beginning of time and never spoken up hoping it was just a glitch or it would right itself! Neither has happened and I’m so sick of paying 17$ a month for something that really isn’t quality! I see so many people complaining on this forum with similar issues and it’s been ongoing since forever and literally nothing has changed so it’s time for me to change !
