Sr Stores — sold fake one plus 7 pro phone and didn't give my 13000 rupees back

Address:

Gate No 5, Abdul Hamid Marg, Malwani Malad West, Mumbai, 400095

I have ordered one plus 7 pro from this company. After getting the product i saw its not genuine. Its a fake phone. I have called the person he told that he needs to check with his supervisor for return. I called his supervisor also. I have asked multiple times to give me the address where to return. But they keep on extending dates. Finally they stopped picking my phone numbers. I want my 13000 rupees money back.
