Mary I purchased a camera when i was Las Vegas, only to find out when I got to the airport it was not the actual camera that I purchased ithey had switched the cameras. in June the camera stopped working, Internet

I was in  las Vegas on vacation, on the last day of the vacation, which was February 18, 2011, my friend and I decided to go into Millenium Foto INC to purchase a camera, the camera I thought was a camera that sent photos to facebook.  I found out after getting to airport that the camera that I picked out and paid for was not the same camera, i had Pentax M10 Kit not the camera I held previously in my hand before paying the 98 dollars. i then had a problem where the camera sttopped working, so I called the number on the receipt and spoke to a lady by the name of Haidee that told me to mail the camera back with a copy of the receipt, so on June 20, 2011 I mailed the camera and receipt by to Millenium Foto INC. A week later I called asking about what they were going to do and they tell me I dropped the camera and I told them no and they said they were out of the camera and that they would get back in touch that was on June 28th. I have asked to peak to the manager and keep getting the run around, so I called again about July 5th, and the manager is still not in. What kind of business are they running or is ripoff.
