(And just to be clear, it has nothing to do with "apology" or any other kind of reported speech; it's just about joining two independent clauses.)

Please clarify your specific problem or provide additional details to highlight exactly what you need. As it's currently written, it's hard to tell exactly what you're asking.

Note that you could correctly say "Sorry, you can return the item to the store." That avoids the independent clause problem.
