Duplicate

I attempted to change my services back in March for TV and internet and comcast for some reason opened an entirely new account for me on top of my other one. Both for the same address and I only have one TV. They have been charging me duplicate invoices ever since then even though I had spoken to them through their chat services many times I had called and canceled while they were on the line twice and this issue is still not being addressed and I'm still getting charged for two Services when I only have one. For some reason even though this should be a simple no brainer no one and I mean absolutely no one has been able to help me thus far and they keep making me go through hoops and call and do all these things and I don't have this time or patience anymore.
