international buildings llc sold me building then send prints that has no engineers seal cant get required permits to erect building deerfield beach Florida

bought this building from this company saying what such a good deal i was getting if i buy right now.i paid good money for this building that didnt even come with ends when they ship me the building didnt even have anything to unload it with just material on a flat bed truck had to unload it by hand.when i get the blue prints for the building it has no engineers seal now iam being told another 750.00 dollars by one person and then i called back and they said it would be 1600.00 dollars by another person at this company. since it has no seal i cant even get permits to erect the building.the building came with no clips to anchor the building which i bought extra that was another 505.00 dollars and didnt even come with anchor bolts.this company is the biggest rip off. WARNING to the public do not have any dealings with this company.it is nothing but a scam to take your money and they should be put out of business.iam sure iam not the only one they have done like this.                     William  Mulberry florida
