TWO QUOTATIONS,1 REQUEST

I requested a quote for 6 standard rooms at RUSTIES LODGE about a week ago and the quotation I got back was R3000 of which I have to pay 50% deposit which was R1500...Yesterday I requested the same quote just to make sure I was on the right track as I had to deposit the R1500,but I received a quote of R6000 which was highly unaccceptable,if by any chance I was charged incorrectly it is not my fault as the budget of the group was already set up accordingly!
