Dear Sir/Madam

Thank you for your recent correspondence regarding non-payment for medicines sent by you to Portugal.

Unfortunately this payment had slipped throughout finance department and it wasn’t until we received correspondence from you that we realised it was unpaid.

I apologise sincerely for this oversight and would like to pay by credit card immediately.

I will be grateful if you could provide me with a phone number so that I can give you the credit card details.

Again, apologies for this late payment and I hope to resolve the situation within the next few days.

Yours sincerely

Barrie John Oldham
