Overall REVIEW regarding your services I will say GOOD...yet one thing that makes me question is in regard to RETURNING oxygen contentrator request which has never been fullfilled. My wife does NOT USE hers anymore (yes I still use mine) and we have called more that twice requesting for you to come and pick up. You still have neve been here to get it. Yes we did make monthly payments until reaqdhing goal of payments and no longer need to send to you money.. Is this ours to KEEP? I frear disposing it being fear if we do it not being ours. It may still be YOURS. Only thought I have what else to do with it is change it into ozygen supplier for large fish aquarium PLEASE REPLY
