Zenith Windows

[HiHo]

Arggh. I've been sucked into having a salesman from Zenith Windows come round one evening - am I really in for the hard sell?

We originally just wanted an 'idea' of how much for our house, as at some point (years) in the future, we may have our existing units replaced.
Fine they said.
5 phone calls from different people to us later a guy turns up for what we had been told a quick measure up, decide style of frame and quote to tell us it would take over 2hrs. Fortunately we didn't have time for that right then but unfortunately we agreed to another time for him to come round.

Should I be looking to cancel this immediately. We've made it very clear we only want a quote for future planning, but I fear the worst!
