My mother, with COPD, has waited for a week now, to get a refill oxygen tank as a backup in case the electricity goes out. Weather reports predicted high winds last week and many possible power outages so we needed the backup to her others. Thank God, the power just flickered and came back on. It is a week and 3 calls later and still no oxygen tank. I hope she doesn t die before we a refill tank.
