DN Tickets Don't buy Disneyland Tickets from this company! Internet

I purchased tickets from this company and they sent the electronic tickets to me. However, when i got to Disneyland with my family, the tickets were not good at the gate. I spoke with a Disneyland Supervisor and they told me that the tickets were purchased then cancelled by DN Tickets, she said you have been scammed. They couldn't do anything for me. I was stuck at the gate with my family and no valid tickets. Tried to reach DN Tickets, they never responded back, the phone number on the web site is not valid. Had to purchase tickets all over again at the Disney box office. Dn Tickets is a complete scam , don't buy anything from them !
