unfair response treatment

I've been using olx for 2 years and never had any problems to advertise my tutoring service to those that needed help and I never had a single complaint,now due to competition some people with bad intentions try to discredit those of us that care about the education of people in this country and thus offer a very cheap service that all people can afford,for the first time in years olx is refusing to post my add and I feel I am being discredited in this manner as I've used the service for many years and all that I've helped only have glowing responses ,the email response eceive is that I need to edit. My advert yet there is nothing wrong with It,it seems to me that either am expericing Damage of character or misrepresentation all I ask is to be alllowed to advertise as in the past so as to reach students that can't afford conventional tutorial companies thanks so much for your platform
