Course Hero AlthoughI cancelled my membership, they did not refund my money. Redwood City CA

I signed up for Course Hero and the next day I had to drop my class so I did not need the membership anymore. I had signed up for a one year membership and cancelled it within the first 2 days of my sign up. I called up their customer serivce for a refund but rather than refunding the full money, they charged me $39.95 for a full month. Similar case, when I had to cancel my membership with Chegg, they refunded my full money without any drama. I do not understand why they had to rip me off for a full month membership when I am cancelling my membership the next day. I was even ready to pay partial but they did not accept it. These people are thieves!
