Didn’t get a job only to be offered the same position from an agency hours later..

I applied to a very large company for a WFH position. I really had my fingers crossed for this one since I didn’t want to go back into the office after maternity. I got an email that they decided to go with another candidate. Fair enough. Within hours I get a call from an agency offering me the same position with the same company for less money and no benefits. WTF.
