Business ProfileforGo-Forth Pest Control

Recently I had noticed there were two air ducts that needed repaired or replaced. I went to goggle to find a ************ saw Go forth is with BBB and had good enough ratings for me to contact. ******** came out looked around in some areas not all and recommended I have new air ducts installed. I was hesitate but As a disabled female I agreed. Cost $6405.00; was installed 8-23-24 by two guys. **** takes the check to office and I get a email to pay for services. To this day I am receiving invoices to pay. I do not understand what is happening. One of the ducts fell the same day. I called for days leaving messages. Finally I had to ask for a regional manager **** and he said he would get someone back out to my home that was on 8-30-24. ****, repaired his coworkers mistake and he and I looked at other areas that needed attending to underneath the crawl space. We devised a plan to have new registers installed at no cost to me which I thought I had already paid for in the total payment. Now I am addressing my concerns and is asking questions no one is interested. I think the size 6 air ducts are too small for my bedrooms. I have a 2 ton unit and think those branching off from the 12, 10 should go down to 8 inch in steps for a 1753sqf 4 bedroom home. I called for days leaving messages. ********* was on vacation so no one knew the details in the estimate fully so my question went unanswered by regional manager. I am again trying to get in contact with **** to give home the details to my bedrooms as discussed no communications whatsoever. Make calls to office staff passes messages but **** the technician never calls back. The company in general has poor communication and customer service support. I think this is going to be an issue for the next 20years that I have a warranty. I think I may have made the wrong decision to have this company to be my HVAC contractor. At this the time I need help moving forward.
