PC from Mississauga

Contacted Sure-Loc after reviewing their work at a friends house even though I was warned not to use them. Salesman measured the area to be done (drawing showed dimensions such as 6 feet by 10 feet) and provided a quote based on approximate square footage and using a stone from a supplier they don't normally deal with however I was assured it wouldn't be an issue. This was due to I had previously used this stone on my front and side with another contractor and had some left over. On the day they were to start I stayed home all day waiting for them and they never showed up. At the end of the day the salesman called and advised me that they couldn't do the job for the price quoted due to the higher cost of the stone. I asked for a full refund and received it. The next day the salesman contacted me again and said that he felt bad for what had happened and wanted to offer to do the job as we had agreed, I hesitate however agreed because I didn't want to wait any longer. On the day of the scheduled installation the stone I ordered was delivered first AM. A crew showed up a couple of hours later to dig everything by hand because they couldn't get a machine into my backyard. Once they were finished one of the owners pulled into my driveway and demanded half the payment. I asked if they were going to fininsh the job that day and he said yes. I asked why wouldn't I pay at the end of the day when completed and he said because it says so in your contract. I paid him half the amount.
