Sony India — sony a7iii sensor dust on brand new piece out of the box

Address:

Hyderabad, Andhra Pradesh, 500003

I am a student of photography and it was my dream to purchase the Sony A7iii. And I realised my dream by saving up money and finally buying it on 6th November 2019. So it has been three days since bought it. However there’s a black dot on the sensor which I can see through the EVF and it’s clearly apparent on the LCD screen as well. I am afraid I got a bad piece. Can you please help me? I purchase it from SVR DIGITAL which is in koti, Hyderabad, Telangana. I really trusted Sony as an excellent camera brand and a pioneer in technology. I spent all my saving on this and am right now sad. Please help me and tell me what is the best thing to do. Peace and Light, Prudhvi.
