Applied Online insurance Quote

I went on line yesterday, filled out questioner and got a $216 quote for my class C. Called today to pay and was quoted $222 to include glass coverage to which I agreed to. Then the “agent” (?) asked if I’d be interested in getting a quote for my two vehicles which I agreed and provided all the necessary information. Agent even said the RV insurance would decrease if I insured both my vehicle. His quote for the two vehicle seemed reasonable but I replied that I’d have to discuss it with my wife before I can commit, however, would like to pay for the RV insurance now.
A slight pause the then he quoted $245 for the RV. WHAT?? Why the increase within 10 minutes? He said he he’s just reading the screen and had no control of the increase. Switch and bait??? Decided to pass on buying insurance .
