We recently place our property solely with Holidaylettings.co.uk, what a mistake!
They are unable to retain our 2015 prices over night, I was putting them back every morning, though this was tiresome, as their web interface is poor.
I reported the problem a few months ago and it is still not sorted.
We would have got booking for 2015 by now with our old booking system, though non yet, which I put down to people not being able to see prices online.
I was told I can not get a refund of my fee, as it is "a known issue", though if they had told me you will not be able to add prices for 2015, I would not of signed!
