Pentagon Federal Credit Union review: Refinancing car loan. Think twice before signing up with them. 1

Pentagon Federal Credit Union offered me a slightly better interest rate for an existing new car loan. I would save about 1000 $. Now, the application was done online and was quickly approved. The problems began later, in couple of month when I've received a letter from them demanding a bunch of additional paperwork and mainly the title with lean holder from the previous bank.(?) I called the old bank and they have ensured me that everything was forwarded to the new bank (Pentagon Federal Credit Union) right away after my old account was closed. Called Pentagon Federal Credit Union again. They suggested that I would have to give them a little bit more time while the document may finally show up in their system. Few weeks later Pentagon Federal Credit Union bank sends me a letter stating that a delay on my part would result in my interest rate to skyrocket to almost 18%. Calling them back. Asked them to communicate with the previous bank. They refused. They don't do such things. But suggested that I call DMV and request the copy of the title. Which I did. It took some time to receive it. Sent them the title. Called them again. Was told that everything now is fine. Later on received the letter requesting additional documents including copy of driver's license and some legal documents to be notarized. Did everything and sent back the same day. Called them latter and was told that everything was in place and no further actions were needed. In about a month checking my Pentagon Federal Credit Union account online to find out that my interest went up to that dreadful almost 18%. Calling them again. Being told that the system is too slow to adjust to finally "recognize" that all their requirements were actually met. Promised to take care of the situation and that the interest would be rolled back to the original level. Instead, 2 days later I have received a new letter informing me that "due to the failure on my part to provide requested documents the interest goes up to 18%. I was furious at this point. Called them. Was asked if I have submitted the requested documents (!). "Yes!". "When? I don't see it in the system" - followed the comment. After I have told them about my frustration the customer representative put me on hold to take time to investigate things. Came back with the "good news": Documents are in the system. No further action is needed on my part. "Things taking time, you know". Promised that the interest rate will eventually go back. Sometime soon. Meanwhile I am penalized by seeing it in my account as almost 18%. That's what their system right now. And I may even get some credit for accruing daily interest depending on when they have received my documents in the first place. This kind of things will be determined as I was told "on cases by case''. Sometime soon. I hanged up. Waiting now for another letter.
