Adding cable router rental to my contract (english speaker)

[PilarLiz]

Initially, I created a contract with the internet and cable router which later I cancelled.
After that, a new contract was created with the same customer number. I would like to add the rental of the cable router Fritz! Box HomeBox6660 to my new contract. Can someone help me in English?
