請英文高手幫忙

I'll try (not sure if that's what you want):
1) You may place any future orders by using our toll-free telephone number, or our toll-free fax number (toll-free usually refer to tele. numbers. Fax numbers always carry a charge) Alternatively, to save our time (that sounds extremely rude! 'to improve efficiency'), (add 'please'?) use the order form provided in our catalogue.
2)As per your request, the following information about obtaining a Hong Kong Special Administration Region (HKSAR) passport has been located.
Either: 'As per your request, the information...has been located.'
or: 'As per you request, the following information...has been attached.'
3)Further to our telephone conversation this morning, a new quotation and order form will be delivered to you some time later ('shortly' would be better). Being printed (this is wrong completely. 'As print-outs' or 'The information as ready print outs are not immediately available at this moment.'), we do not have them immediately available.
4)Remember, (again, sounds extremely forceful, I'd cut this word out) we are the only catalogue sales company that guarantees your full satisfaction. If you are not completely happy, pleased or (cut out) satisfied, we will arrange for a prompt refund, credit or surrogate ('replacement' would be better). We will also refund or credit all shipping costs associated with the returned items.
5)Between the period of 1 and 30 April, I made nine small purchases. Three of these purchases were given telephone approval granted (can cut out) by the bank. When I received my last statement, (cut this out. Traditionally, one cannot start a sentence with 'when' in writng) a copy of which is enclosed. I was flabbergasted to see that I was charged $100 each for these purchases because my account was over my limit. (I was astonished to find that each of these purchases were charged $100 due to over-spending. A copy of my last statement is enclosed.)
