Ajio — Unable to cancel the undelivered order

Order ID : FL[protected]
This was ordered on 14th July and it is at the same status it was on 15th July. The delivery date at the time of order placement was 16th then 18th then 19th then 21st then 23rd and now it’s 28th which is also past due. And I’ve raised multiple complaints with them but still there is no response and they are not even letting me cancel the order.
Please assist me in getting the refund and getting compensated for the harassment they have been doing from past 2 weeks.
