Canada Safeway
Not paid my wages

I work on a sat or sunday morning shift and we get paid every thursday. for the last few pay periods i worked sat and sun yet was only paid for one of those days. when i spoke to the manager he told me that it wasn't on the time card. yet they don't keep track of the cards and they are gone so there is no trace of my hours. safeway is ripping me off and i am now putting in my notice. they will not pay me . for hours i worked. they say i didn't work them.
