Sovereign Lending group appraisal scheme Costa Mesa CA California

I recently received a call from Sovereign Lending group and worked with Joshua Brindle so my wife and I could get a decent refi done on our mortgage since our interest rate was going to be adjusted to 8.5% the next month.  Everything seemed to be going fine until it was time for the appraisal.  I had discussed with the loan officer that the value of our house should come in around $500k.  This didn't seem to be an issue with him.  So when the appraisal was finished he explained that the appraisal came in way too low.  He said it should have come in at $550k in order to complete the loan.  My wife and I were angry but moved on to another lending company.  We explained to our new lender that we had already had an appraisal done and that we had paid for it.  When it came time to close with the new lending company they refused to release the appraisal and explained that it is their policy not to release conventional loan appraisals.  Never mind that Kamron Rowland who is the director of operations indicated that he would release the appraisal.  Now he is going back on his word.  This makes no sense to my wife and I since we paid for the appraisal.  My feeling is that since the loan didn't work out for them they will make it hard for us and the new lender.  Sour grapes!
