thanks again @MortenCopenhagen for your kind information. I know about the maps forum but it takes a long time but if I post in there 2/3 working days solve this problem so my always the first choice is Connect forum. and you share another link sorry to inform you that Bangladesh till now not available facility. Have a nice day
@MortenCopenhagen has provided the correct answer, the Maps support community is the place to take data issues that cannot be fixed via the feedback system. I will thus be marking his answer as the solution.
