This company sells oxygen supplies I had originally inquired about a portable oxygen machine for my husband several months back. My husband went into the hospital and they set him up with a in home oxygen unit, I let this company know there service was no longer needed 2 1/2 months later they still call almost every durning the week there’s days where they might even call 2-3 times!!!!! I’ve asked nicely on three separate occasions to be taken out of their system that their service is no longer needed each person says sure no problem will take you out of our system I’m still receiving calls so now I just block the number through my iPhone it stops my phone from ringing but I’m still able to see in my call log where they continuously call and then every so often they leave a voicemail I think it’s safe to say at this point it’s har**sment and definitely beyond annoying!!!!
