Ferns N Petals — order no 7898984-not delivered

My order no. 7898984 was supposed to be delivered today. But it was not delivered and the reason mentioned was address could not be found.

For your information address was 100% complete and other companies like amazon, flipkart, archies, flower aura etc. Have been delivering orders to the same address without fail.
I tried to call customer care multiple times but it was busy even after waiting for more than 5 minutes each time. I even wrote a mail to which i got reply stating that the order has been considered executed. This is absolute fraud and such companies should be banned from operations.
