Apology letter for delay in delivery of stationary due to transport strike

From,
Mr Jerome,
Stationary Supply manager,
MMRDA Stationeries Ltd,

To,
Mr Jackson,
Principal,
Don Quixote International School,
Philadelphia

Dear Mr Jackson,

I, Mr Jerome, the stationary supply manager of the MMRDA Stationeries Ltd, apologise entirely for the mistake from our side for the untimely delivery of the goods and the stationary products which you have been ordered from your school. The transport strike which took place on the National level last week resulted in the delayed arrival of our consignment and hence the delay got relayed. However, it was us who committed on the delivery of the goods and the stationary products ordered and hence we take entire responsibility for the delay and accept it as a lapse in our service.

I assure you that the mistake will be taken care of in the future and there shall be no lapse in any context in the coming future. I hope that the continuity of healthy business relations between the two of us is maintained in the coming future. Apologising once again,

Yours sincerely,
Mr Jerome
