I bought this product last Sunday.

I bought this product last Sunday.
I checked if I could trade in what I was using before, and I told the clerk that if I bought a product over 5000 yen, it was free for one trade-in and decided to purchase.
On Wednesday of this week, the item before it arrived through another shipping company was confirmed as "Is it possible to trade in?"
Today, after two hours in the afternoon, the store has contacted me twice, and is it an application for repair? It is said,
No, I explained that I had purchased a new product and asked for a trade-in, but I was asked the receipt number and the name of the person in charge to confirm the call and ended the call.
However, after an hour or so, there was no contact, and I contacted here.
An explanation was given to the call center and another person returned and apologized.
In that person's story, coordination with a shipping company? The problem seemed to be that the store contacted us due to lack of confirmation.
Until I hear the situation of the store later, I do not know what it is, above all I just listen to the receipt number etc.I do not come in contact, the person on the first telephone left without confirmation I was angry at my irresponsibility.
I don't think that there is anyone who buys basic appliances as long as there aren't too many appliances.
Consumption taxes are rising, and customers are increasingly choosing a store.
Please make the shop where the after-follow as well as the product knowledge is fulfilling. Here in Namba! Please make a shop that seems to be.
You don't have to listen to the story of a person who makes you a great customer, but I want you to deal with each and every thing properly as a shop in the future, rather than leaving it like this.
