Missing Item!

I am writing regarding my online order placed on 26 May. I received my package yesterday; however, one of the items I was charged for was missing from the delivery.

I have attempted to contact your office by email and telephone but have not received a response.

Could you please investigate this matter and advise when I can expect the missing item to be delivered or alternatively how this issue will be resolved?

I would appreciate your urgent attention to this matter and look forward to your feedback.
