TUSTIN, CALIFORNIA -- I have never come across a more negligent company. I call their service 2-3 times per day and request to not deliver a certain type of Oxygen Canister because the doctor ordered the wrong one. They deliver the wrong tank anyway (which my mother cannot lift to use)I call some, apparently mentally disabled woman named Mireya 4 times and she assures me that it is on schedule to be picked up. Around 4pm after my mother, who is deaf & cannot hear the doorbell, so she sits and waits for them by a window ALL day, tells me they have not been there. I call them only to find out that it was NEVER SCHEDULED! I call dispatch & finally someone on that department offers to pick up the tanks on his way in to work the next day. This is ALWAYS the case w/ this company. They're not going to get until they get sued!
