Dolphin Carpet and Tile received the wrong tile and they refused to credit me for the opened boxes! they dont tell you, Internet

Stay away from this place!!!! I dealt with Randy and Vincent in their South Miami Store, talk about a tag team!! I requested some samples and they said I had to order a box of each of the tiles, but not to worry, I could exchange them for the tiles we liked later. I order 4 boxes at a cost of $100.00;  once we decided on the tiles we were told they couldn't take the "samples" back, even if the boxes were not opened!! but they would be "working with me" to reduce the $100 off my total order.
 
I should have put some distance between these thiefs and us, BUT... WE DIDN'T. we place the order and the first 3 of 25 boxes were picked up by our installer, who got to work with the three boxes, but when I saw the tiles, (already installed) I realized they gave him the wrong tiles!! they refused to refund our money and refused to cancel the rest of our order.

we also ordered 4x4 inserts and received the wrong color, we are still waiting for them to resolve that issue. bottom line, they have no concept of customer service, they will trick you into buying tiles you never ordered and they will refuse to cancel orders and refund your money. STAY AWAY-STAY STAY-STAY AWAY!!!!!
