Multiple Accounts and can't link them.

I recently moved and used the move service which was working fine. I had it on my xfinity account and the wifi was up and running. Then they sent me an email that i had a service tech scheduled so I called and wanted to cancel that, in the process I also wanted to make sure that the service at the old address was cancelled. After that call my internet went out and my account was all messed up. In the proccess of trying to get this issue resolved multiple accounts for my new address were made. I finally got the to activate the internet on the newest account but I can't link that one to my account were I'm a gold member. So my monthly charge has also gone up. I'm sick and tired of calling in and explaining this over and over to only continuually getting transfer and losing connection or being told I'll get a call back. I'm very close to cancelling my service and looking else where because it has been days of phone calls and chats. Who can I speak with that can resolve this issue?
