Termites treatment

They promise you 5 years for termite treatment and say if the termites come back before the five years is finished then they will come again and treat your area without any questions and no cost. Guess what, not even a year finished then boom termites are back. So like the agreement, we called them and they came and sorted it out, a few months later termites again and still they came then it becomes a norm now that after few months they will come and treat termites. It's not even two years yet and now they are tired of coming to treat the termites. Now they giving stories of it's costing them to come and treat. And the guy becomes arrogant over the phone. He told me as the husband that he's been dealing with my wife all along and he doesn't see where I get in now here and that's after I took over the talks from my wife. So if they promise you 5 years of treatment, rather have them put it in black and white as to protect yourself.
