Disgusting service from sterns Phoenix plaza

I ordered an earing online, choose to pick up at a pick up point when I got home I had proceeded to open my package to which then I discovered the earing was a babies earing which was meant to be a gift for a grown adult which is simply silly as my whole order including other items from other stores had gotten messed up I then called the online department to which I am aware you cannot exchange earings for hygiene purposes but I had spoken to a guy from online who assured me I can take it back since it was the wrong thing and un used and also was just a day later I had taken the earing which packaging and everything to sterns in the Phoenix plaza which a guy tried to assist was not very helpful then went and proceeded to get a lady whom he claimed was the area manager who was not helpful at all I explained the earing was wrong she then told me she cannot take it back due to policy which I do understand no good business would be running without policies what I don't understand is how can someone from the online department tell me i can return this yet this area manager made me leave the store with the earing she then **** to me and said she had logged a call for a pick up of the item from me however today I receive a sms stating my issue had been resolved what sort of bull**** is this I am still sitting with the earing which I did explain to her was a gift for someone whose birthday was this week i am utterly disappointed that an area manager would behave in such a rude and unpleasant manner ,being in customer service your duty would be to help a customer to the best of your ability which neither of them did ,in times like this where we are facing a pandemic every sale counts and if this is the way customers are treated what customers would you have returning back to such outrageous behavior, please look into this as I'm very disappointed in sterns Phoenix plaza area managee and the guy who was in store on Sunday 27th June.
