Orkin in Canada Pest Control

We hired allpro Maple Ridge to treat our 12' x 15' shed (stand alone guest room) in June of 2014 for carpenter ants and were told had a 1 yr warranty. Ants were seen in the spring of 2015 and I called them. The receptionist gave me a very hard time, said I hadn't paid enough to get warranty. I emailed copy of receipt to her. They came and sprayed again june 2015 but it had no effect, in fact we were inundated with carpenter ants and had to get another company in.Very displeased with this company.
