I messaged them today regarding a withdrawal pending since Friday. The reply I got was that it should be approved by the end of next week

The annoying part is, I made a withdrawal of £70 a week earlier. Through frustration i reversed it a couple of days later and increased it to £220. Did the same again and turned that into £300. Unfortunately I am now down to £100.
It would be impossible to convince me that this isn't the real reason for the delay in processing withdrawals. Keep your money and leave it where you can easily get at it. A bad practice in my opinion for any site claiming to promote responsible gaming. Dr. Vegas has now lost a(nother) customer. I have never waited more than 48 hours on the other sites I play.
