I would suggest we are having some

I would suggest we are having some language difficulties – I amended my invoice to show 14 days storage at total of $640.00 because that is how I read your e-mail requesting (see attached)

There are 7 days of storage and rent charges applicable here in Mombasa that have to be paid by yourselves. These are in part from CMA and in part from Kenya Ports Authority. This container sat in Mombasa port for 2.5 weeks, naturally there are going to be additional charges.

So now see attached the previous invoice I sent which shows the correct amount for rent and storage.
