Poor Service - Holiday letting Client

I wouldn't recommend using their services to anyone. Rather go with airbnb they are 1000 times better. I have called through to booking.com numerous times with issues regarding my holiday unit listed on their website. They always ask a series of verification questions and then say they will need to call you back in order to proceed "for security reasons" and then they never do. I honestly do not understand why they need to call back, what is the purpose of security questions then???? Meanwhile after not calling you back, they also ignore any messages that you send, they also now inconveniently to you as a client, no longer have an email address, so in other words they will take your money but will make it as difficult as possible for you to reach them or get any kind of service for the monies which they are making off your property every month. Airbnb is a way better option as they assist you then and there and all issues are resolved timeously. Their commission fees are also much lower than booking.com. It is very disappointing to receive such poor service despite the thousands in commission fees which I am paying throughout the year for bookings made on their website for my holiday accomadation. Seroiusly considering removing my property from their website.
