a joke

a joke

An object of ridicule, contempt, or dismissal, especially due to being inadequate, defective, or not genuine. Their customer service is a total joke. I was on the phone for nearly two hours just to be told that they couldn't identify the problem and wouldn't help me any further. I spent nearly $800 on this phone, and it stopped working after just a month. What a joke! Their offense would be pretty formidable if their quarterback weren't such a joke.
