Daya Ram and Sons,
Dear Mr. Rant,
I have received your letter dated complaining about the electrical goods we supplied to you.
Usually, we sent only those items which have passed strict quality control specifications. It seems that owing to some oversight the materials lying in the rejected boxes were despatched by our staff. I regret and apologize for the inconvenience caused to you.
Kindly return the defective items so that we may replace them with newly manufactured and approved ones. You may deduct the freight charges incurred on you.
With best wishes, assuring you of our best service in the Future.
Lala Har Narain.
