Teleperformance (Toronto) coerced me into accepting a different job : What shall I do?

I can't believe this is happening to me.

Last week, I applied to a technical support advisor position. They called me within a week asking me to do a technical test (which I passed) then fast tracked me to a zoom call with HR (where I was selected). So far so good, then they send me to this recruiter who sent me a job offer and asked me to accept while she was on the phone.

I always read my contracts before signing. I just read the first few lines when I discovered this was a conditional offer for the role of 'agent'. This seemed vague to me. I politely asked her about it when she basically went apeshit.

"This is all you get" "quit wasting my time, if you dont want, then leave. I will give 1 more minute to accept it" I kinda froze not knowing what to do or say. A minute passed by like this... I glossed over all kinds of conditions and clauses.... then afterwards she blurted out 'times up' and almost like knee-jerk reaction I clicked 'accept'.

She audibly irritated said something beneath her breath and just hang up.

Its been 9 hours since it happened. Its 3am now and I still can't feel easy about it. I know I need to work to pay the bills but I just make myself agree to work for them.

Does anyone know what I can do or should do?
