Pay back my money

I ordered 4 platters & 100 samoosas for a party on 11 November 2018, from Colorful Parties, and had paid the full invoice amount quoted to me by Arno of Colorful Parties for my order. My order and delivery details was again confirmed by Arno on 7 November, and my order was supposed to have been delivered on Sunday 11 November at 1pm latest. I DIDNT receive my order on the day, and was unable to reach Arno the Sunday. To date i have not received my money back. I am unable to get hold of Arno of Colorful Parties.
