Retired — Cannot login to gmail account

I can not log onto my gmail account: [protected]@gmail.com. I have tried several times to log on. When I could log on there was an unknown network on my account. I would sign the network out and change my password. The network would still come back. When I signed out of my email account the sign out box, would be on my desktop page and I would sign out again. I created a new email account : [protected]@gmail.com and the unknown network is also on this account as well. I am making a complaint because My Gmail accounts are hacked and, I can not get any help to resolve this serious problems. My telephone number is[protected] Thank-You Cleo Browne
