No communication

I have very disappointed at service I have received from Ariva. I app**** through Ariva a week ago was approved on the 4th only after I had to call and find out what is happening with my application after they finalised they still didn't contact me to explain the terms of the contract nor on what vehicles are available. Again after me phoning and trying to get the right information they sent me the wrong quote upon receiving it I called as they vehicle was incorrect and was told it is the correct vehicle just to find out by the dealer that's it isn't, again calling asking them to fix it just to be told we can't we on training for the next two days will see if we can assist. Upon calling there head office there is absolutely NO ONE who is able to assist as they all at a conference. How the do you run a business like this can some please explain and get this sorted TODAY.
