Subject- Complaint about defective an air purifier

Respected Sir,

On May 15, 2023, I made a purchase of an air purifier with the model number [Model No] and the invoice number [Invoice No].

The purifier was delivered last week, however after full installation, it stopped operating. I think the product is faulty because of how quickly it was delivered. Even after properly installing it and carefully following all the directions in the provided manual, it still won't function. The purifier also appears to emit a little amount of hot air, which confirms the flaw.

In the upcoming week, kindly send your expert to fix it and, if necessary, have it replaced with a new, functional item at no additional cost because the payment has already been made.

Wishing for a prompt response.

Thanking you,

[Your Name]
