Harman India — Cancellation and refund for the order HA-IN00155012

Address:

Harman International (India) Pvt. Ltd.,Marathahalli Ring Road, Bangalore-560103, Karnataka

Respected Sir,
The order HA-IN00155012 was placed Sep 26, 2020 from harmanaudio.in and I have been made more than 6-7 follow-ups with harman customer support on the call and email to cancel that order.
The first intimation was given on Sep 27th 2020 on the email to harman customer support to initiate the cancellation and confirm me on the email as the shipment was not even initiated.
It has been 7 days now and I have not received any communication/confirmation on the call/email about the status of my cancellation or refund.
There has been no reply from [protected]@harman.com. No use of calling[protected] to check the status.
There was no use raising any service request like TN-E[protected].
Also, there was a failed transaction from my IDBI account and I have emailed harman support to see the transaction code which was failed and initiate the refund.
There has been no reply or communication for my concerns till now.
I need this communication to be considered as my official intimation to them to address the customer concerns
