Because of my deep dissatisfaction with this company, I am writing my very first internet review. When I called to make the appointment, I was specifically told that if I purchased the pet pre-treatment at extra expense, "If the spots come back, we come back." There was no mention of a time limit; I believed that I had a reasonable time. However, when I called after a little less than 90 days to report that the spots had returned, I was told that there was a time limit of 30 days. The representative refused to honor the guarantee. I cannot recommend this company.
