Comcast equipment

Hello! I have canceled my account due to an international move. I have returned my internet equipment, but in the shop, a representative mentioned I also had TV equipment that I had to return. That information was absolutely incorrect, and I told so to the representative. They said It must have been a mistake and that was fine. But I am still receiving emails about the equipment I should return. I am not in the US right now and I cannot call Xfinity to talk to a representative. Would it be possible to fix this by email? 

Thank you.
