Ackermans womens do not cater for people in wheelchair

I am in wheelchair and bought sleep pants 4 pairs I am paraplegic and can fir into fitting rooms and need a bed to try on. At home I fitted 1 and it is not comfortable so I took the 3 that was stil on the hanger back end kept the one I tryed on.

At till I was not informed its underwear and cant be returned so what do I do know?
