Independent Practice: (revising a complaint letter) -- The following complaint letter does not abide by complaint letter writing guidelines. Rewrite it fully, applying proper complaint letter format and content requirements. Hey you!! Yesterday, I purchased my bmw car from your car dealership in beirut. It is very miserable that I had to write this letter but really i was shocked from the car that I purchased from you, when i tested the car I was surprised that not all the seat belts buckle up, one of the door latches is broken, screeching noises arise when you turn the steering wheel, and the windshield wipers do not sweep completely.I trusted you and paid to buy my dream car from you, but really I was dissatisfied with this bad service. I want your honor to refund you as soon as I return you the car this week. I look forward to your immediate reaction.. No regards, cheater! Angry John
