Sanitech Disappointment

AVOID IF YOU CAN!! Arrived at 16:25 after booking for 08:00. Needed two tanks completely drained, they partially did one and left. Came back the next day and completed that same first tank. But due to how full they were, the tanks are still not cleared. Came back a third time and refused to do either of the tanks and left. Over the years I have never had an issue with them, what has changed!?! When a client needs the tanks drained, then drain them as required, even if it takes multiple loads for the tiny truck. Not that difficult!
