www.oxygenplusmedical.com review: They didn't change orders

I ordered parts from the company www.oxygenplusmedical.com. It was bad experience, ‘coz they took money from me and provided the completely wrong parts. I tried to return them, but of course the rep refused and told that it was my mistake. Also he added that the never changed any items. The company is really unprofessional and the rep didn’t care about the customers. So be careful if you use this website or leave comments if you have horrible experience with this seller.
