Domino's Pizza — ambiguity in management resulting in not following their rules

Address:

Bagalur cross Yelahanka, Bangalore, Karnataka, 560064

Dominos is well known for their 30 minutes delivery guarantee. But this was my first experience of having got it late. I called them and informed them about it and they assured that i would get the money back within 5-10 days as i paid through amazon pay. After that period i called them for the refund and they told i would get a call. I got a call and now they say there is nothing that they can do.
