Preferred homecare Over a period of 7 months they over billed me many times Nevada

I had a hip replacement surgery don june 7th 2017 and they supplied a walker for me at the hospital. The insurance info was given to them in july I recieved a bill for 23 dollars and change for the walker. Then in september I recieved a bill from them for 57. Dollars and change from them for the walker. These bills were paid by me immediately.

Then january 2018 I recieve another bill from them for another 10 dollars by now I am seriously irritated that they just keep sending me bills. I call there billing dept and they argue with me and tell me to just pay it and shut up. They were the rudest place I have ever dealt with

. So i paid them and asked if the account wa now paid off they said yes so I told them to close the account and they said they cant close the account and to bad. They wont do anything. If I recieve another bill from thee thieves I will sue their a**es off.
