Ring Tours - incompetence and poor service

First time in Paris , suppose to be magical! <br> Thanks to the incompetence and poor service of Ring tours our memories won't be so great!!!<br> Booked a Dinner and show at Moulin Rouge for the first evening after our arrival with Ring tours through Flight Centre UK. <br> Arrived at Moulin Rouge all excited only to find out that a reservation on our name does not exist, after spending our evening on the phones with Flight Center and trying to contact Ring tours we had to leave. Apparently Ring tours doesn't operate over the weekend and have no emergency line , leading to no availability on behalf of the company to confirm our booking which was paid a month in advance.<br> Absolutely dissapointing service! Avoid at all times!
