I myself have used *****************.com a several times. I have been very happy with untill the last two times. I had a Burberry bag to authenticate. They are very quick in resonding, and seemed very professional. I got the authenticity certificate within 30 hours and I was very excited for my bag turning out authentic. However, I started doubting the authenticity because the bag style is nowhere to be found on the internet. I contacted them and they said I have to order another authentication if I want to know the exact style of the bag. So I did. I even attached a message where I explained the bag has been previously authenticated by them and that I'm only doing another authentication to figure out the style. It took couple of days for them to get back to me. I got an e-mail from them, saying it is authentic and I received a certificte (another one). And that was it... Not a single word about the extra service I ordered. Not a single word about the style. They didn't even bother to tell me whether they found out the style. So I contacted them right away, saying that I have paid for another authentication just to figure out the style. I got a response, saying their were not able to find out. I did definitelly did not appreciate them "forgetting" to even mention that in the positive authenticity e-mail. The lady then contacted me again, saying she will refund me the extra charge I paid for finding the style of the purse. WOW. I found it very unprofessional. They knew I only ordered the same authentication twice to find out the style, and yet they went ahead charging me the full price after not being able to find out, and not being able to inform me about that! Very disappointed.
