Usually it is the people with bad experiences that are po'd enough to write reviews. I am sure there are many more that have had good experiences that don't both to yelp.
I moved from Vancouver to Toronto in 2012 and the process and service was great. Most of the reviews here seem to be able "conditions" that they ignored or were not aware of...like fuel policy. I had no issue with it. Fill it...period. Go to a gas station, fill it and drop it off. Simple.
The truck was running when I arrived and the place was closed too. So what? I checked the truck and drove away.
In fact, I plan to use this company again when I move back to Vancouver from Toronto this year.
