Unblocking drain leaves raw sewerage in garden

<p>Rescue Rod came to unblock a drain. They said the modern way is to use water pressure. I was dubious and rightly so. The blockage was right there. The sewerage got blown up and out of the nearest open drain next to where they were working in the courtyard. They then "washed" the raw sewerage into my garden and doused it with Jeyes fluid. And for this I have been charged R2537. A few years ago I had the drains unblocked and never had this problem. Rescue Rod seems to think this is OK. I think its unhygienic and a health risk to humans and pets. </p>
