Tata Motors — Cancellation refund rs.5000.00 not settled

Address:	Tata Tafe Access, Mount Road, Chennai
Website:	cars.tatamotors.com

I have booked Tata Tigor (P) XZA+ New online in Tatamotors website on 5th Feb 2021. details below.

Model: Tata Tigor (P) XZA+ New
Color: Arizona Blue
Portal Order Ref: TTIWyV[protected]
Payment Transaction No: VSCB[protected]
Dealership: Tata Access + ANNA SALAI
Amount Paid : 5000.00

Due to some personal reasons I have to cancel the purchase and requested for a refund. They have asked me to write and submit a letter to Tata Motors - Anna Salai branch. I wrote and provided them the excuse letter (for cancellation and money refund). They said the amount will be refunded in 7 working days.
However, through several follow-ups, I haven't received any refund or status updates from them till date.
Finally, I have no choice other than registering a consumer complaint here in this forum. Kindly, help me in getting this money refunded.
