I order a cake and bouquet from flora sensation on 10 February and make a payment via phone pe after then I got an order confirmation mail. After sometime I got a mail of cancelled order and in that mail it was mentioned that I will get my refund in 10 -15 Working days. Today is 29 February and till now I didn’t received my money back. I had mailed flora sensations like 10 times but no reply received. Kindly look into the matter and process my refund asap.
