I would like to add my experience in dealing with Dave.
After weeks of trying to unlock my wallet without success, I turned to Dave's wallet recovery service as my final resort.
He replied quickly and was able to unlock within the day. He moved all my coins out of the previous address and when I provided him with the new address, he send me the bitcoins in full (minus his service fee).
If he was dishonest, he could have kept all the coins as he had full control of them.
Thanks Dave for your quick response and service.
