Work issues

Okay I work with 2 older woman its literally just 3 of us. We clean r.v's and cars etc. For the past 2 weeks they just refuse to talk to me and our job we have to talk to see whats done and whats not and they haven't said not even one letter to me in 2 weeks. Its to the point where I really want to quit. They are older then me im 28 and they are almost in their 50' s and act so immature like what do I do? Should I quit? I just feel uncomfortable here or stick it out or how do I come about asking what is the issue here.
