Vendexa Products — ultrasonic pest repellent

Today 3rd august 2020, i received ultrasonic pest repeller ordered from vendexa products and was delivered by delhivery.
The product is of very very poor quality.
Now i don't know where to return this product.
The company doesn't have any website or customer care services.
Nobody but it please. It's pathetic.
