It sounds to me like the agent in the city where the seller has moved has sent the listing as a referral to an agent in Mt Pleasant- so there is probably a referral fee involved- another issue could be that it is not actually listed in the MLS but a type of pocket or non exclusive listing and another one of the problems could be that there is no shared co-broke for the agent you have representing you. As Chris has said your agent should be contacting the listing agent and/or the local agent or both of those agent's managing broker (and maybe even the seller's if they are not being co-operative)
Best of luck to you,

You don't give us much information to go on. Is this a new construction site? Sometimes builders have a registration policy which requires you to indicate on an initial visit if you are currently working with an agent. The idea being not to use the site agents time unnecessarily if you will not be using them.
If you worked with a site agent and the builder has this policy, you may find getting other representation difficult. Apart from this scenario I'm not aware of anyone controlling who you wish to represent you.
