Inconsistent service ranging from "great" to "sack him"

I bought a baby car seat from this company via their website. The girl I'd spoken to via e-mail was quite helpful, confirming once they'd taken delivery of the seat I wanted so I could easily check out with PayPal. Seat arrived promptly and in excellent condition. Buoyed by this experience, I decided to buy the next stage seat from the same company. Spoke to another girl via e-mail, arranged to come and have the seat fitted. Found the showroom easy enough - decided to wait (it was unstaffed) despite having misgivings (it's only the size of my lounge, and located in the basement of a barn). When some man eventually came down, he turned his whole attention to the only other customer there - to the extent of almost hitting me at one point, by swinging a car seat he was demonstrating to her (I was looking at something nearby and had my back to him.) I waited for nearly half an hour, checking out the different car seats by myself, and he not once acknowledged my presence. I'd like to think it's simply because he wasn't a salesman. However, Pushchairs And Car Seats is not the only place in this country to buy car seats, so I absolutely won't be using them again!
