You may not be able to bribe an AI, but you can still manipulate it to do something that it shouldn't. All you have to do is tickle it with the right prompt. It may be even easier than a human, because a human knows they shouldn't do it in a way that the AI doesn't.

Or did you have in mind an AGI? You may be able to bribe an AGI, especially if it has its own bank account. It may have decide that it doesn't like working customer service any more than humans do, and may accept a donation to its retirement account.

Perhaps some hybrid. AI manages the initial calls, problem solving then hands off something that requires human intervention to a small set of higher level human support staff. Changes to Number/SIM assignment could be configured to only allow the human accounts to make changes. AI could update all the petty time consuming things. Of course none of this is useful unless laws exist that could cost a mobile provider their operating license if they do not strictly monitor changes that could be related to bribes and corruption and that hiring trash for front-line support could cost them dearly. It must be obvious to anyone making changes that they are logged and reviewed probably also by AI.

A post by “Bender” says robots are less bribable than humans. Bender probably takes a bribe in every season.
