They can say whatever they want but if someone publicly says or writes anything factually untrue and it damages you, you indeed can sue for slander, libel, defamation, interference with business relations etc. -- or at least threaten to do so and give a warning.

If you threaten suit they may cease all such false comments. If not you indeed may be entitled to collect damages.
