That is quite shocking tbh.....
I was fortunate enough to have the opposite experience (I won't name despite being a positive experience, as it is a competitor) - I bought a 450D cheap from an online retailer, on the understanding that it was used - it had about 200 clicks on it and was absolutely immaculate throughout (every bit of packaging was as new, including all the cables in their bags etc). Saved 25% on even the cheapest online price at that time!
It thought I was lucky at the time - now I think of myself as even luckier, having read this story.....
Glad it's sorted now
