Dulles Kia

Traded and purchased new Kia Sorrento. They could not take a rear tag out from the traded vehicle at the moment, so they told me that it will be mailed to me next day using Fedex. Tag never came to me a take a rear tag out from the traded vehicle at the moment, so they told me that it will be mailed to me next day using Fedex. Tag never came to me and checked with the dealer and sales person, then he told me that tag was directly sent to MVA. Few months later, I was contacted by MVA that rear tag was never returned!!! So, the dealer and sales person was lying whole time. Now I am contacting the dealer and sales person and I told them what I need. Basically a letter saying what happened, so I can submit that to MVA. Sales person told me that it will be mailed, but letter never came. Now I am trying to contact sales person and he never picks up the phone or return me a call back for more than one month!!! What kind of professionalism is this? I will NEVER go back to this dealer, even for a service and will not recommend this dealer. More
