PhonePe — money have be sent to wrong number.

Address:

Hyderabad, Telangana

Sir/madam, I have done a transaction of 3k to a person through PhonePe regarding a product, after receiving the amount the product is not delivered and the pwrson put my number in block as both my phnepe attached number and number from which i called is same . I have raised the issue with customercare of both Phonepe and my bank . Both of them are escaping the issue by saying that the issue can be solved by other.
I am a student. Can you help me in regaining the amount.
