I bought 2 Thomas Kinkade canvas s on last cruise 5/25/2018 and when I got off the cruise called the company to verify my order and was told I was getting a cheaper version than told on cruise and not the size I was promised! I was told I was getting the last 28x42 canvas s. To find out he ordered me the 18x27 pieces which are even smaller than what was on the cruise even! Now that I want to cancel cause I was lied to and bait and switched they want me to pay 15% fee even tho nothing has been shipped or processed yet! Also prices are half as much to buy direct from artist! I m filling claim with B.B. and my credit card company!
