Sears Carpet & Air Duct Cleaning Furnace filter is left on the corridor of the basement Lorton Virginia

I engaged the services of Sears on 3/22/2016. A service planned for $154.95 to clean 14 air ducts, the technician suggested cleaning of furnace and all that lead to a total bill of $1,379.65 which I paid immediately. After cleaning, he said my filter is dirty, at first I was surprised its not already included in the bill, but I agreed I will like to change the filter, and he promised he will make an order on my behalf. I guess the old filter should have remained in the furnace until a new one replaces it. However, I returned home from office only to find my old filter on the corridor of my family room. I have tried the technician's number but no response. I have called customer care but the lady hang the phone on me after my complaint. The new filter ahs not arrived and I have to confirm that my furnace has been covered without a filter for 2 days by the Sears cleaner. And Sears need to suggest to this or I press charges for this. My Sears invoice number is 101416. I have not entered the utility room yet. Sears services is a rip off. Be careful !
