It seems that we sent the product that was supposed to be sent to you to another customer.
We found out today because a customer contacted us saying that he received a product that he did not order.

I think it was due to a simple labeling error by our staff.

I have felt that you are a close customer because I have been in touch with you via e-mail a lot, so I am really embarrassed and sorry about this incident.

I would have sent you a new product immediately but unfortunately, we are out of stock.
I have contacted the manufacturer but am still waiting for their response regarding the shipping date.

I will contact you as soon as I know when we will have it in stock.

I sincerely apologize.

We are planning to review our checking system to make sure that something like this will never happen again.

I fully understand that we have caused you much inconvenience. I know that there are other sellers that offer a lower price than us so I understand if you decide to cancel the order.

How would you like for us to proceed?

I look forward to your response.
