Is working in customer service for a dish TV channels company (CNE) unlawful (haram)?

The ruling on cooperating in selling tools depends on their intended use:

If it is known that they are only used for the forbidden (haram): Their sale is absolutely prohibited. If they are only used for the permissible (mubah): Their sale is absolutely permissible. If they can be used for both permissible and forbidden purposes: If it is known or highly probable that the buyer will use them for the forbidden: Their sale to him is prohibited. If it is known or highly probable that the buyer will use them for the permissible: Their sale to him is permissible. If the situation is unknown: One should consider the prevalent custom among people; if their use is predominantly for the forbidden, the sale is prohibited; otherwise, it is permissible.
