Mahindra And Mahindra — Lack of response from Dealer regarding Refund and Tax invoice

Address:

Hare Krishan Classic Car Cares Pvt Ltd, Mulund West, Mumbai 400080

I had purchased an XUV 700 from Hare Krishan, Mulund West on 18th February 2023. I had inadvertently paid an excess amount of Rs.21, 591.
I have sent 3 emails to the dealer (27th Feb, 9 Mar and 13th Mar) and spoken to the concerned customer service team on 28th Feb, 10th Mar and 13th Mar. Finally got the tax invoice yesterday after a 2 week delay but no communication regarding the refund till date.
