hello Nynke010
Welcome to the community.
It’s kinda hard to tell it the cable connection fee is included. Since I am just another customer and have no knowledge of your contract.
In general the fee is included, if you have a contract for internet, tv and/or phone. In some cases people got a refund for the connection fee by UPC. Sunrise doesn’t do that.
I’m sure, @Sunrise_Team might be able to look into it and give a more refined answer.
