Laptopexperience Did not protect customer interest Tampa Florida

I purchased a Laptop of value 142 bucks from the seller..The seller noted he sent the Laptop through Fedex and package was delivered at home address.. I did not receive the package to date nor a refund of my money since the package was declared missing by shipping agent.The seller should have requested a signature at time of shipping for a package of high value so buyer can assume responsibility of the product..The seller failed to protect the buyers interest and so i could not get the package nor a refund..So as a consequence of the sellers irresponsibility, i am at a loss..I am very dissatisfied with the sellers business ..The seller lacks consumer trust due to its unprofessional business practice...I strongly would advice any potential customers out there to stay completely away from any type of merchandise purchase with this company..
