Address:

Basavakalyan

I had ordered oneplus 7t on 23rd march, but due to lock down it got cancelled. As ot was a prepaid order i was supposed to get refund before 8th april. Amazon customer care executive says that "the reference number was created and amount should have been reflected before 8th april". The refund reference number is #589147. Please help me out it's been twenty days and the amount is 34999/-
