I saw a add regarding Nikon d5300 recently. I spoke to the person through WhatsApp he had given his number.
He agreed to give it to me. But I stay in Bangalore and he is from Odisha.
So he told he will send through courier I agreed and he had asked me for full payment. I told I'll pay half and the rest after the delivery he agreed for that. But after I payed he isn't replying to me properly and he is asking for full payment.
So I'm asking him to return the money.
Please take some strict action against him.
I thought Olx is best and not like other sites. But I'm wrong I'll provide his number and his I'd proof.
