Went to walmart and purchased an HP Deskjet F380 Ink catridge at 3:02pm (as per receipt). The model HP Deskjet F380 is the printer I use at home and so the sales associate checked the ink catridge box and CLEARLY saw it on the box hence that was the correct ink catridge. I got home (3:30pm) only to realize that the catridge does NOT fit, indicating that it was a manufacturer's defect.

4:02pm - I returned to Walmart only to be told by a manager called Nathan that they wouldn't accept the return because it is an open box. I clearly explained to him that and showed him the evidence I had on hand indicating that the model number and what was written on the box were the same as confirmed by the sales associate and myself. This arrogant, non-professional manager called Nathan, instead of him using his common sense as a manager, only rattled they would not accept the return. I paid $30.42 for this!!! I need assistance to retrieve my money back.
