Poor, expensive survice

This is the 2nd time I'm using RentoKill for ants. The first time was neither bad nor good. The initial treatment was on time, yet no stock on bait stations that I paid for. The follow up treatment appointment was missed and not communicated. They eventually arrived just before it started raining and still did the treatment. The result is that the ants are now worse on some places. The so-called bait stations are R14 units that I paid R160 for. They placed 3 of them in a small area and then my dogs destroyed them the same day. I just feel that the money spent is not worth the service and that a pre site survey before quoting might have eliminated some issues. Busy getting some quotes to actually solve my ant problem.
