Robert our delivery person is great, he is kind and happy to answers questions. They have been out of the oxygen tanks I need two weeks in a row and could only provide a few. The delivery day gets changed when they run low and since you must be home to take delivery and sign, I have to rearrange my schedule to accommodate their incompetency. My account needed to be transferred to a different location after the initial delivery, it has been 8 months and it is still not done so I receive texts from the wrong office saying to expect my delivery the next day and nothing gets delivered, so then I have to call and wait more days. I'm now told there is a billing issue so the account is on hold while it is under audit and they cannot transfer it. Do not call between 12 and 1 p.m., you'll be left on hold the entire time because they're at lunch, but the recording does not tell you that.
