Herko Exhaust Gas Recirculation (EGR) Valve EGRV430 for Ford Mazda Mercury Ranger Escape B3000 Mariner Tribute Sable Taurus F-150 3.0L 4.6L 2001-2008

I called herko automotive to find out status of an ordered part. Tracking number said shipping lable was cancelled. The first customer representative was helpful and easy to talk to. He needed to talk to someone else to get more information and said he would call back in 15 minutes. I went to the post office and the part I ordered was in the PO Box. I called back to inform Herko my part arrived, and a different customer representative answered. He refused to hear anything I said and continuously told me I would need to call a different number. He was extremely rude. I tried to call him two more times to explain that he could disregard my initial enquiry. On the last call, I was able to explain to the first customer representative what the situation was and the rude customer representative joined the conversation and told me he was going to block my phone number and said I was harrassing them. Very unprofessional.
