      Complaint Type:
      Product Issues
      Status:
      Answered
      We hired Mills Engineering LLC in April 2023. We provided all necessary information for a septic design & site plan. It took several emails, texts, and phone calls to get them to start our project. We finally made payment on 06/06 for the project. The septic design was completed, but the first draft of the site plan still wasn't done. On 08/31, I emailed the project manager, ****************, asking the status, and she stated she would speak with ***** and get an update because it had been several weeks since ***** stated, over the phone, that we would have the first draft. ******* stated she would speak with ***** on 08/31 to find the status of the project. No answer from *******, no response from ***** (same exact problem as before with the septic design). I e-mailed again on 09/02, nothing, e-mailed again on 09/06, still nothing. E-mailed again on 09/13, still nothing. *****, Patch Construction, spoke directly with ***** and was promised a site plan draft to us on 09/20, and still nothing. We keep getting promised the first draft and never receiving it. I finally texted ***, engineer at Mills, on 10/3. He responded he would contact *****. I spoke directly with ***** on 10/6 she stated she would have the first draft to me that day or no later than the end of the weekend. On 10/6, ***** said she would send over the plans to *** to complete the first draft. I asked *** if ***** relayed to him that I was to receive the first draft by the end of the weekend. And he confirmed that she stated that. I texted *** on 10/12 asking if he had any questions. No response. On 10/19, I texted I still had not received anything, *** responded and stated he would give me an update the next day. 10/20, *** stated ***** would give us a plan today, but Monday at the latest. We still have no plan and it is 10/30. They've had our stuff since April and it is October and we still have no site plan. The address on the state website is NOT the address of the business.
