Rude till lady on 25/02/2021

I have been treated so poorly by the lady behind the till after returning an item. The item was found broken after the plastic outer layer was removed by me at my house. The lady accused me of breaking the item myself, stating that I removed the plastic to vigorously and so braking an almost 2cm thick wooden frame. I will not be going back here and I was a good supporter of their shop because it's situated next door to my office.
