The owner does a poor job of communicating with her employees. I sent a check for $72.00 last week to cover the cost of a lawn treatment and a $10.00 late fee. I've been a Harmon & Sons customer for at least 20 years and this is maybe the second time I've had a past due payment. Long story short, I mailed the check on May 20th, and the afternoon of May 22nd got a call from the owner stating she had looked for a check from me and couldn't find one. She then proceeded to threaten to assess an additional late fee on my account. I called Harmon & Sons less than 1/2 hour later and spoke with the business owner's accountant, who assured me that my check had been received on the 22nd as promised and my balance was paid in full. Very unprofessional of the owner to say she couldn't find my check and tell me she would assess additional late fees because of HER mistake. Maybe she should have checked with her accountant before calling me! 5 star product, 2 star customer service.
