Service 4 Appliances

I paid $340 for service to my LG dryer which was not drying clothes properly. They took apart the dryer and said it was completely serviced. Now 3 months later it is not working again. They say they only warranty their service for 1 month! They were not willing to come back and even look at what the problem is without pre-charging me $80 for the service call.
DO NOT USE THIS COMPANY. THEY HAVE VERY POOR CUSTOMER SERVICE AND OVERCHARGE WITHOUT ANY REGARD FOR THE SERVICE THEY PROVIDE.
