I have claimed the warranty on the website of the boat that some problem has started in my airdopes. After that xpressbees dilivery service take my product.
After 1 month i call dilevery boy
and he(Akshay pal dilevery boy) said they lost my product and they give me 2 choice
New product or money.
I choose money
And I also talked to his head about it.
Then it asked for a few days' time.
i said ok.!!
then i call to the head on saturday
then he says (ranjeet sahu xpressbees head),
We are not giving money, do whatever you want to do("hum nahi de rahe paise apko jo ukhad na ho ukhad lo")
