Can I receive unemployment if I quit, due to the job not being what I was told at hire?

The company that I work for recently laid off many hundreds of people, including me (the company lost a big contract).

I was given 3 weeks notice. A week before my last day, they offered me a temporary position working for a different client of theirs, at badically the same pay. I was told by the recruiter that I would be doing the same type job, in a similar industry (customer service and sales inbound calls for the telecom industry), so I accepted it.

During my first day of training for my new positon (2 days ago), I was told I had been hired not for regular C.S. & sales, but to do retention of customers (something I have not done before and don't feel comfortable doing). My offer letter did not state that my duties would be different from my previous job or contain a job description, and the title did not include the words "retention," "saves team," or anything similar anywhere in it.

After spending a few days in training I do not feel confident that this is a job I can do to the standards required, and am continuing to seek employment elsewhere.

Would I be able to receive unemployment if I quit, due to the positon being different from what I was told verbally by the recruiter and in my offer letter? Would this be considers good cause? (This is the only position available at this time, so I have little hope of getting placed into a positon like my old job by talking to management.)
