Domino’s Pizza complaint: Free Pizza

Long time customer with my Ventura Ave. Dominos, after my latest order I received a E mail informing me that I got a code for a free med. 2 topping pizza, I used that code to order this pizza a few days later for Pick up I only live one block from Dominos. Gave them the order was informed that it only worked online, ok I went online to with code even ordered some bread also, the computer said it not working for a take out only for delivery, so much for getting a free pizza its $ 5.99 for delivery (great strategy by the way) ok ill said ok for delivery here comes your overkill, you not ordering the minimum, the message says its $16.99 minimum for a delivery order. I called back, asking to speak to the manager, the employee said the manager cant help me. I will never use Dominos anymore this is the rippoff of the century. Its the principal .not me asking for handouts. Shame on Dominos I will write reviews about this in every way i can ,Iam a business owner and will tell who ever I can about this scam Dominos uses to make money , my free pizza would have cost $16.99 plus $5.99 for delivery its a joke.
