I am currently having a negative experience with Bitbays.com.

I had about 300 USD in my account and asked at the beginning of November 2015 to withdraw them to my bank account.

After 1 week, I had still not received any funds in my bank account, so I contacted support.
Support took 1 week to reply something totally irrelevant, like instructions on how to request a withdrawal.
I replied and told them again that the withdrawal had been requested (and it appeared as processed on their website) but that I had not received it on my bank account.
Another week and a half later, support told me that there was a problem with my bank account (seriously ?) and told me that they would refund the money in my Bitbays account.
After a couple of days, I still had not been refunded the money in my account, so I contacted support again.
After another week support told me that they would chase this up.
We are now another 2 weeks after they told me they would chase this up, and still no trace of the funds neither on my Bitbays account nor on my bank account.
I am sending an email to support every week about this issue.

So my conclusion, based on the irrelevance and slowness of the Bitbays support, is that you should beware of this website.

It smells like scam.
