Qatar Living Website

I have been using the classifieds section of this website to sell a few things before leaving the country and having a lot of difficulties with the website. For example, I tried to post a picture of my car that was for sale and when I downloaded a picture of the car, someone else's photo was there. I kept having to remove the bogus picture. I reloaded the picture a number of times and finally got it to work correctly. Today though, someone else posted the same kind of car for sale and either listed my phone number by mistake or the website automatically put my phone number in the ad. I had to turn off my phone and over 100 messages later, the phone calls keep coming to me for someone else's car. This website is so, so, so frustrating and not very user friendly. Another problem is that when my car did sell, I wanted to mark the item as sold or take down the ad, but I would have had to search through all of the ads to find mine. There needs to be some way for users to quickly find their ads and have access to them.
