Ring doorbell, will not complete set up

I have previously had this device set up on my home broadband network. I took it off the door to charge it. When i put it back on the door it wouldnt connect. I havent changed my wifi password/router placement. I deleted the device to try and add it again. I get through to connect my phone to the doorbell, i select my network, enter the wifi password correctly (there are no special characters only numbers and letters, and yes i am making sure that this is correct with all the right upper and lower case etc...) i get the annoying message about "rome not being built in a day" then it says there was a problem and that it cant connect, suggesting it is the password... it is not the password. I have also tried a second wifi network i have available, and it will not connect to this either. I am generally good with connecting devices, as i have set up a variety of smart devices in my home with relative ease. I have been trying to set up this doorbell for 2 hours now... Either provide a fix or i would like my money back please.
