Apple India — poor service levels

Address: Venu regency , Waltair road, Ramnagar ., Visakhapatnam, Andhra Pradesh, 530003

I have bought a earphone adaptor from imagic Ramnagar Visakhapatnam, it was a faulty one. I returned back the product to them and they said the amount would be refunded through google pay !! I’ve been chasing them but there is no response from the management and their contact does not work at all !!
They being authorised seller for Apple, sold me a first copy product and me upon asking them all they gave was a grin with no proper explanation.
