Drain surgeon call-out fee exorbitant

We dis not have water for a day and when the water returned, our geyser was dripping. We called drain surgeon. Their service was good, but I find their call-out fee exorbitant. The cost of the repair was R2000 for 10 min work of which R1600 was the call-out fee. Quite ridiculous. Have already located a plumber that charges R500 call-out dee. Will not use them again.
