bad service and blaming the customer for it

On the 1 of July I made a booking at Elohims Lodge and Spa and was qouted I made the 50% deposit as it was required later I get an email from them telling me I was qouted wrong and that I need to pay more,who's fault is it that they sent a wrong qoute and still when I accepted it they did not see anything wrong. So now im stuck with the fact that I must look for another accommodation!!how rude and they way they deal with customers is wrong and needs to be dealt with!
