Moving Services Limited

As all of the stories I read here, I too became Victim to this company. Was told for my 1 bedroom move it would be $200 for 3 hours and additional hours would be billed at $45/hour for 2 men and the truck.
Movers were over an hour and a half late, asked for a $300 deposit which I would be reimbursed if I didn't go over the 3 hours.
Once all items moved and in Truck ready to head to new location they gave me a bill for $1150!
(It had only been 1.5 hours at this point)
Now with all my items in the truck, and me alone by myself they refused to move until I paid the balance. I spend 30 mins trying to speak to someone initial guy who booked told me to call 'supervisor Mike' who was extremely rude and told me if I pay $671 he would have the movers complete the job. (I should have called police at this point). After getting to the new address they offloaded my items and said they would not be bringing them upstairs unless I paid another $450. At this point I had had enough and was not going to give them a penny more. So after paying $671, I was left for 4 hours to move my entire load alone. I wish there was something I could do to prevent others from going through this horrible and stressful experience.
