Cancelled Device Care Complete but am still being charged for it?

Hi, I am in a bit of a pickle. I am very in debt and currently dealing with a battle to get on disability - so I cancelled my Device Care Complete in the hopes that it'd help me save a bit of money each month.

I was also trying to get a hold of someone to talk to about Connect for Success (or whatever the low income plan thing was, my roommate is also disabled and has it) but I do not have the luxury of waiting for hours on the phone. :( So I am hoping to get in touch with someone who can assist.

Is there any way to get my billing fixed, like by contacting someone over live chat or email? Most of my chat support attempts are not delivering, I'm trying to use the website chat support and it's just giving me errors when trying to contact an agent. Keeps saying "Not Delivered" and erroring, haha.

I unfortunately cannot afford to pay off the full bill atm, so I'm hoping the Device Care Complete can be removed like it was supposed to be. If someone can lend a hand I'd appreciate it. I cancelled it over a month ago. 

Thank you.
