I've been practising English. Because my English has not been good yet so please help me if you can fix errors in my short passage. Thank for your kinded first.

The first passage is a letter :
KENDAR OFFICE SUPPLIES
Ms. Pranee Udomsak
Director
Beni & Beni, Inc.
426 Silom Road
Bangkok 10110
ThaiLand
Dear Ms.Udomsak:
In checking our records, I noticed that you are no longer listed as a current customer of Kendar Office
Supplies. When I called and spoke to your office manager, Peri Davis, I was informed that your
company is now using one of our competitors for their office needs. Ms. Davis referred me to you
as individual who makes all purchasing decisions at Beni & Beni.
Ms. Davis kindly described some of the problems that led you to select another supplier. I'm pleased to
tell you that Kendar has made many improvements to its product line and services, and we are certain
Beni & Beni will find these attractive. We have introduced a whole new line of office and computer
supplies, many of which they are not available from any other supplier. In addition, Kendar now has
the largest warehouse facility in the region.
For you need any additional information please feel free to contact me. We are welcome the opportunity
to serve your company once again.
Sincerely,
Quoc Thang
