Me: We've been experiencing intermittent issues from one of your services.
Tech: OK, we restarted the service. Is it working now?
Me: Yes, it's working, but it's been intermittent, so we don't know if it's fixed.
Tech: OK.
5 minutes later....
Tech: Is it fixed?
Me: Well, it's working, but it's only been five minutes so we don't know if it's fixed.
Tech: OK.
5 minutes later.....
Tech: Is this issue resolved?
Me: ......
Eventually, they decided it was simpler to refund my two year old phone than to fix it.
