Honestly speaking, I havent been able to get the time to see the videos but I will surely do that.
In a nutshell…following is the process:
You sell a product and it has a serial number.
If a product gives an issue to the customer, if it is under warranty, the customer gets back to you with the product, you give him service number/tracking number for its repair status. If the product falls in warranty, its repaired free, and if it is not (like burns etc) it will be charged.
And after that
If a product is not in warranty, the customer will be a repair/tracking number, when the repair is done, the customer will pay the price of the repair.
This is the complete process…
