Query: missing parts

The antenna is great, pulls in more stations than my old rabbit ears BUT, on delivery, was missing a critical part. I contacted Audiovox and they sent a part, but it was the WRONG PART. I contacted Audiovox again; their customer service tried to convince me I didn't know what I was talking about. Finally, after multiple transfers and being kept on hold, their technical support division backed me up and I was mailed the right part. This took two weeks!!
