Black suitcase & outfit left in taxi

Hi last Saturday I got a taxi after the Bellx1 concert outside Vicar St, when the taxi dropped us off, he drove off before we could get my belongs from the boot. An easy mistake but I really would love to get my stuff back as the siitcase is full of items with great sentiment value, Including my canon powershot G7X containing lots of family photos & my iPhone 4. There was also a separate hanger with s grey dress, black leather waistcoat & black belt. Please please can you let me know if you have any imformation....I'll happily give a reward to get my belongs back. Thanks a million, Aine 00447581485372
