Attorney / Lawyer in Bogota, Columbia

I need some help with my business. Looking for an Attorney/Lawyer in Columbia, preferably in Bogota. A client from Bogota placed an order on our Amazon store for an item. After his shipping forwarder lost the package he was given a full refund and $25 Amazon gift card in exchange for his satisfaction and not to leave negative feedback. After the client got the refund and gift card he left negative feedback against the agreement and is trying to extort our business. His negative feedback is causing damage to our online store. Looking for an experience individual in Columbia who can come up with an interesting idea to contact the client and make him remove the feedback. The idea can be to file a lawsuit or anything else that will make him understand that it is in his best interest to remove the feedback as promised. We believe that a single phone call can get the job done. The client, name, phone number and email address will be provided. A bonus will be awarded upon success.
