Disclose all relevant T&C's and policies at point of sale or Accept return

I bought a bluetooth speaker on the 26March 2020 and it stated that it has a 1 year warranty and the speaker stopped working in January, with all the kids going back to school and us parents going to work we got busy such that the time went on however on the 25th March 2021 my husband took it back with its box and a receipt and a lady Bianca refused to take it saying we messed up the charging port and I wrote an email complaining to their site ref nr 569126 and someone responded saying she is Rochell Carolus saying I should send pictures via WhatsApp pictures of the speakers so that the buyer can assess the damage if it's made by a customer or what and that Suprises me because the item is still under warranty and there is no where it was written that return it if blah blah even at point of sale nothing was ever mentioned and I feel very dissapointed by this . I bought many things at Checkers hyper now am worried what's going to happen with all the other items if they don't honor the warranty they go back on their word. I am also noticing inconsistency because my neighbor returned something and none of this was done to her and I don't know if its color or what.
