Subject: Complaint against defective goods
We regret to inform you that the mattress we had purchased from you is bringing a lot of complaints from our customers regarding its poor quality of foam.
According to the written and the telephonic complaints of our customers, the mattress looks head and tends to tear off very easily and also is shaggy. All these complaints confirm that the mattress provided by your company is of poor quality and below standard. We are eagerly awaiting your explanation regarding this matter.
