Still be singled out by OLX

This is an update on my previous OLX complaint regarding them not posting my add due to me using stock photos (while literally 100's of other adds selling the same product are using the same stock photos). Finally after sending a few emails and posting a report on here Michelle called me on Monday (22/06/2014) and said she was unaware of other adds using stock photos. When I asked her to search from the product on OLX she was surprised that I was in fact rite and she found tons of the same product using stock photos. She asked me to email her a link of the search page and she would be sure to take it up with management to get the matter resolved and get back to me. Well surprise surprise its now Friday and all the other adds using stock photos are still up, Michelle has not gotten back to me and my stock photos are still not allowed. WHY AM I BEEN SINGLED OUT OLX ???
