Brake Disc Caliper problems of the 2010 Honda CR-V

The vehicle was purchased new Honda Cr-v 2010 and has been services throught same place purchased since day one. The complaint of a "metal noise" dropping when reversing. I have replaced the tires, brakes, calipers, drums and rotars as they siezed, wore unevenly and "oxidized(?). I have been told the tires have an impression on them as the vehicle must have been not used for a period of time. The care is used daily. Some excused provided have been amazing. Main point is that the transmission/metal noise continued while I drove the car or when my cousin was going to use it (but declined when he heard the noise) when the care goes in for servicing "noise could not be duplicated" I would leave and get home unstatisfied and due to responsibilities in life make it difficult to just go right back out to resolve the issue. It got to the point that I would take the vehicle out for test ride. Finally when I duplicated the noise. Repeatedly/annually complained and was not found until having the vehicle for over a month (gsh did provide loaner) I have returned to the service center since the car has been there, but continued to leave my car there. Now they want me to pay the deductible ($100) an additional fee for new transmission of $1510. 00. This is a problem I had documented on every service since I purchased the vehicle. . When in reverse and proceed to reverse the metalic noise drops but the car still goes in motion. There were two times it did it in drive. Every service visit was routine and sceduled; recommended services were done on the spot, not when I would return for next oil change. . I am just disheartened and saddened that they have taken advantage of this female customer. . . . I have been made to feel that this would not have happen to a male customer.
