BloomsVilla — Flower

I ordered flowers from website since I wanted to gift it to my colleague.I selected delivery slot 12-3pm on July22, 2022.
But after payment was done this slot automatically changed and it became full day any time flowers will be delivered...
When I tried calling customer care
No one answered
I mailed them to cancel the order since they provided me with wrong info...and also requested to deliver it on Monday instead of Friday they did none and it's 10 pm at night no flowers delivered...I want my money back
