Bad billing practices.
Look they do great work. My problem is the billing. In the fall they billed me for work I asked them not to do. When I got the bill, I sent them an email asking for them to remove that part. No response. They continue to send me the bills for it till I sent an angry email. They apologize, fix the bill and we move on.
Six months later and there is a 3 month gap where they don't send me a bill. When it finally comes, I pay all three months online. Right before I go on vacation, they don't come to the house. I figure I messed up the week. I come back from vacation and no work was done. I email to ask my account status. No response. I receive a bill. It says I did not pay those three previous months. So I recheck everything and find that the online payments all have the same invoice number and it is not mine. Crap. Something got messed up in the online system and it looks like I paid someone else's bill. I email them with copies of my payments, which I also verified were withdrawn from my bank account. No response.
Two months later I have moved on to another company and figure this place just doesn't care. Then I get another bill saying I still owe for the three months minus my previous $70 payment. What???!!!!! I did not make a $70 payment on that date. So it looks like my payments don't go to my account, but someone else's does?
Obviously something is seriously jacked up with this account. I understand mistakes happen, but it is the lack of response that is causing this conflict to escalate, just like it did last time. There you go. Good lawn work, bad billing.
