Prompted for nline checkin, but no comms to advise that one has to be early for aggage manual checkin time

Why are custoerms allowed online check in when their booking has laggage if they still have to be 40min early for laggae checkin? At least advise a customer that is doing online checkin that they still need to be early for laggage checkin. This gives an impression that the customer has fully checked in and doesn't have to worry about manual checkin. Ts and Cs do not matter when a different impression is provided. Why do you even prompt a custer for online checkin when they have laggage already paid for in their booking. Now my laggage is going to JHB with my husband while I go to EL becuase it was either that or miss the flight waiting for the nxt day flight whole I do not have accomodation in cape town. I would like a refund for my laggage payment please.
