Olx India — Fraud IPhone seller

My brother make a deal with sabir Ahmed about iphone and and I send 29000 via google pay for phone but I didn’t get the phone . He said there is problem with courier service and he want me to pay customs duty also for giving me the product.
When I ask him for courier details he gave me a mail ID
[protected]@gmail.com fo enquiry and he didn’t give me any track ID also
