I have posted two advertisement in olx.in so far. But still I dont sell anything on olx. The whole system is good but here is some problems for the users.
1.In the first two or three days you can good response of your advertisement but after few days no call or response are showing because they started new advertisement promoting program.
In this thing you can promote your advertisement on the top page for 15 or 30 days for giving them money. But it is the bad thing for the people who dont spend money on olx for selling advertisement. After few days there no response of the not paying advertisement and this is a major issue.
