Olx — oneplus 7 fraud olx

Address:

Surat, Gujarat, 394101

I was in search of a second hand/ refurbished mobile phones of oneplus company. I searched on olx, i got an ad which was attractive and was seeming a good deal with 20, 000rs oneplus 7 pro, i message that dealer.

He insisted me to message him on either whatsapp or contact directly via call.
I asked him, why can't you talk on olx messages? He didn't reply.
Then i messaged him on whatsapp and started a conversation. He told the price of oneplus 7 pro as 20, 000rs initially, then he told, now its sale time, so its available for 16, 000rs. And i also asked the price for oneplus 7 mobile phone. Replied, its 13, 000rs. For oneplus 7.

I also asked, which this mobiles are so cheap? He replied, its refurbished pieces for they are sold cheap. I insisted him to lower the price. He agreed on 12, 000rs. I told, how would the payment, he told, cash on delivery. Then i thought, its cod, then there might not be any issue.
Then at the time of ordering, he said, you need to pay advance for delivery. And he also told that as soon as i pay the advance (1, 000 rs.), he'll provide me the tracking id of the couriour company (Delhivery.com). Then i thought, he is providing the tracking id as well. He would be a real person selling this phones.

Then unfortunately, i placed order, and paid 1000rs. Online via upi, then after 5 minutes, he provided me the tracking id. And yes, it was real.

The twist was, when the courior arrived at my home, delivery boy told, he would first take the money and then allow to open the parcel. I gave the rest of the money (11, 000rs.) cash to delivery boy, and opened the parcel. I was shocked.
It was a "itel mobile" (Worth 3000rs.). And told to delivery boy, that its not what i ordered. He replied i cannot take back the broken parcel.

I immediately called that dealer, he replied, it might be a wrong delivery. He said, "i will report to you within few hours how this happened.".

I actually had recorded while unboxing the parcel. And i also send that recording. After a day, i called him for status, he replied, sir, it was a wrong delivery, your phone was delivered to another person, and that person's phone was delivered to you. Then i asked, when will i be getting my ordered phone?
He said, you'll get a mail, and you need to send your name and address to that mail, to file a complaint. And i did so.

After 2 days, that dealer gave me another number, saying it's our complaint department number. I called them, they told, that my phone is wrongly delivered to another person, and until we get that back, we cant deliver it to you.

After a few days i again called, they gave me 10th oct as the date, when i'll receive my ordered phone. They said an executive from our company will come to your house and give you the product.

On 10th oct. I waited a lot but no one came. I was also calling continuously, and they were telling, till evening, you'll get your product. But no one came to deliver.

Today, on 11th oct, i called that dealer at noon, he told, yesterday, the executives and complaint department was on leave. So you'll get your product today.

But today also no one came. And in the evening, i tried to call them, they were not giving proper answers and also not relying on whatsapp as well. And they blocked my number as well.

The mobile number of that dealer: +[protected]
Complaint deaprtment number : ‎+[protected], ‎+[protected].

Please help me to get me my 12000rs. Back.
