RETURNS POLICY AND CUSTOMER SERVICE

So I wanted to exchange a pair of jeans that I have bought in December for my son. It was one size too big. I was informed by the manager that it was after 30 days and they are unable to help me. Instead of asking me question about why i didnt bring it back sooner or why didnt i send my son, ask me what am i going to do with a jeans that does not fit????Nor could i see any returns policy period on my till slip. Not impressed at all Legit Baywest Mall . I did not want money, just an exchange .......
