Jessica Robinson 25 Miller Road Sacramento,CA、95852 Dear Ms. Robinson, We recently received an order of your new modelAngle Grinder, which your salesman advised us to offer as part of our handyman range.Although we have only had them in stock for the last two weeks, we have already had 3 returns.Customers have complained to us that the locking ring simply does not work properly, which causes the disk to fall off. You can imagine our embarrassment. This is truly a dangerous situation, and we suggest that you stop supplying this item immediately. You should also issue recall notices. We are returning the entire order. Most of them still in their boxes. I realize that your power tools are generally of very high quality, so I hope you sort this problem out quickly for the sake of your reputation. Please issue us with a credit notice for the entire value of the order. Yours faithfully, Paul Richman Store Manager What is being sent along with the letterA、proof of purchase B.A、copy of the invoice C.A、refund request form D.An entire order of the products
