Roto-Rooter Sewer & Drain Service

Good service, no problem there but when i had called RotoRooter it was specified there was a $24 service call and $68 an hr plus GST and parts, no mention of anything else. The plumber only charged the service call as he flushed the toilet and it worked. I thought it would be $24 plus tax, but he said "Oh no, there is a $24 travel fee and the $24 service call plus tax". Why is there no mention of the travel fee? I ended up having to go to the bank as I had to use up the cash I had on hand. People cannot read minds and I think it is deceiving not to reveal all costs.
