Is there CPP, EI on part time? ?

I work as a part- time telemarketer earning 10 cad/ hr 4hr per day, Mon - Friday. I joined a company since Nov 1 2008. I was getting the cheque bi-weekly. For Cheque I received in Nov 2008, there was no any deduction on the cheque. In Dec, they didn't pay me coz they said they will pay my Dec 2008 cheque and Jan 2009 together at end of Jan. On Jan 23, they pay me the cheque for Dec 2008. But they said I won't get money for the work I did in Jan 2009 because they use the money to pay my CPP , EI. They never give me doentation of CPP EI deduction. And I did not have any benefit from the company at all.
