Business ProfileforIndustrial Electronic Repair

On 04/24/24 electronic controller component was received by company for repair. A service agreement was emailed on the same day, indicating that the unit had been tested and a $500 Zelle payment was required for the repair. I sent the Zelle payment. No report was forthcoming as to the component's malfunction. Attempted to call numerous times, leaving messages with no response until April 29th. On that date I asked for the unit to be returned if the reason for the unit's problem couldn't be conveyed. I received an email message from "****" specifying the problem, but he indicated that the unit would be shipped back requiring a $250 COD payment to **** I emailed ****, reiterating the reason for requesting the unit to be returned and instructed IER to repair the component if they were confident that certain transistors had to be replaced. Had a phone conversation with "*****" and "****" on 5/1/24 asking when repair might be completed. **** fabricated a story that I was arguing with "several" employees and decided he was done dealing with me. He sent an email to that effect on the same day. The unit was returned and a refund was issued. I discovered that the company had taken out the transistors and not returned them with the unit. When I requested the transistors, "****" refused to send them. Another company was unable to repair the unit because of the missing transistors. IER did not respond to the other company's request for the transistors over a course of almost two weeks, nor were they willing to provide the values of the transistors. The application for the component is now totally useless.
