Myntra.com — Order get cancelled automatically just one day before delivery

I have ordered some Mcaffeine skin care products from myntra. As per tracking it reached till my nearest delivery centre and now they suddenly cancelled the order and reason they have given is "We had to cancel your order due to unforeseen circumstances." I have wasted my 5 days tracking it and now it will not be delivered, totally unacceptable and unethical behaviour from myntra. Myntra should add a tagline to there app and website "Ruining your occassions with unforeseen circumstances." I want the products to be delivered within given time frame or double the price I have paid.
