i paid for four matching boat seats on 4/3/17 at a cost f $2300.00 it took 6 weeks to get them but one of the four seats was the wrong color they told me to send it back and they would send me the correct seat but its been two weeks now and when i called they said they were going to credit my creditcard back for the one seat i told them i need all four seats to match and i wanted to return the remaining three seats and cancle my order they said they were sorry but the seats were non returnable and now its been 10 weeks and still no matching seat this company is a rip off they took $2300.00 from me and i did not get the full order i paid for and they tell me sorry nothing they can do for me because they are just a drop order company what good is three seats on a boat i need four matching seats i think they knew they only had three matching seats and thats why they sent me the one seat in the wrong color there customer service does not return call I wonder why because they dont want to hear all the complaints they are getting for ripping customers off
