Ferns N Petals — cakes and plant not delivered refund not paid

On 11th july cake and bamboo plant of cost rs 1218 was ordered from fern and petals to be delivered on same day. They cancelled it twice and were unable to deliver till 13th july.
After a lot of deliberation ferns & petal according to them initiated refund on 13th july which was suppose to be in my account within 7-10days
It is been 14 days and i have still not received the amount in my paytm account
Not only they have poor service but operating are fraudster
