Let me start by saying I like honest people. Both my daughter and I purchased a voucher from Groupon for Pest Control by Assassinator Pest Management. On arrival Ray checked our meter box and advised that we still had 2 years on our existing pest control as did my daughter. Ray advised that the treatments last for 10 years and advised that he would contact Groupon and request that we both receive a full refund. We will certainly be using Assassinator Pest Management in the future. Thanks Ray
