Dear Ms. Colon:
I want to apologize sincerely for what is currently happening with the latest delivery. I am genuinely sorry that shipped items have been delayed for three days and have not yet been delivered to you as scheduled. Such cases are unacceptable and go against our principles of partnership. We value cooperation with you and want you to know that we are currently working on a solution.
I want to inform you that we are working on fixing the issue at the moment. It means that we analyze all possible causes of the delay and check all our channels associated with the delivery of the shipped items. These include everything related to delivery technology as well as the people responsible for the package. It is essential to mention that our professionals already identified several possible causes, so it is just a matter of one or two days for the parcel to arrive at your place. Regardless of the actual cause of the delay, we will refund shipping charges by Thursday.
Again, I am very sorry for the negative experiences you received during our last collaboration. We will soon find the root of the problem and apply the appropriate solution. Rest assured that this would not happen again. Moreover, I need to remind you that our company is committed to reimbursement of all costs associated with the delayed delivery. I also want to inform you that a new package will be sent to you that will arrive by Wednesday. Your early reply would be appreciated.
Sincerely,
[Sender Name]______________________________
