What's your seat post like is it knurled?
I had the same problem with the Qu-Ax Ali frame and the black UDC post.
I tried a few clamps, with no difference in the slippage. So after
realising that the post wasn't knurled, I cut shallow grooves in the
post with an angle grinder, upto the height I have the seat. Since then
it has been fine.
