Myflowerapp — Not issuing refund and response by the company via emails or calls

I did order 2 orders of flowers bouquet and chocolate on 08/05/2023.
The delivery should be happened on the same day which never happened and they didn't have the courtesy to inform via any modes of communication.
I had to call them and check and their excuse is that it's very far and cannot deliver. A staff picked the call and she wasn't ready to hear my comments she just hung the call.
I emailed them about the issue and the refund. According to them refund will be done, when that cannot answer. Till date they haven't reached back neither the refund.
Worst service ever!
