Lowering fence height

[Bodgejob1]

Hello, I'm in need of some quick advice re lowering 3 fence panels we have just had installed in past couple of days. We have a sloping garden, down towards the house and in the past. 2 days a fabulous landscaper has installed 10 and half 6 ft panels on 150 gravel boards and overall it's brilliant. However, we have decided we have made a big mistake in installing the closest 3 panels as 6ft as with and extra Drop Of 2 ft to the house we have effectively an 8ft fence. My question is, is there anyway we can lower the existing 2 and half panels without removing the newly sunk posts or is it a better option to remove them and install 5 ft panels?
Or do I have to take the whole 3 posts and panels out and start again on the last 3.
To add insult to injury the neighbours the other side have dug in a drop so they have the entire 2 and half panel length as an 8 ft drop which I can't machine they're thrilled about....
Help!

Are the posts slotted or not and are they timber or concrete?

i assume they are padded out with extra gravel boards or other timber underneath
if they are slotted posts and no fixings prop the panel up about 1"[or enough to get a saw in] above the boards
cut the boards near one end and remove
