Good to know there are no wires. For the record... the screws don't push through the tape. I needed to scrape it out with a sharp knife... something I was reluctant to do... and frankly shouldn't have had to do.
I understood what they were trying to say. My point is that they were
1. wrong. The screw just doesn't push through. And I wasn't about to stick a nail or screw in there without knowing what's behind it.
2. dismissive. They might have fewer issues if they listen to customers.
Anyhow, the problem got sorted eventually.
Thanks
