I haven't done much investigation but it looks like a business problem
between AS15964 and AS6762 or a configuration problem in AS6762.
There don't seem to be any IPv6 announcements visible from AS15964 in
the global table but there are IPV6 announcements from AS6762.   
AS6762 has a looking glass at
https://gambadilegno.noc.seabone.net/lg/lg.cgi which shows the
2001:4268::/32 prefix.  (The looking glass says "Not advertised to any
peers" but this seems to be configuration of the looking glass rather
than a true reflection of policy.  The looking glass says the same for
2800:870::/32 which is globally visible.)

Where did you look to see that 2001:4268::/32 is being announced?
RIPEstat sees the prefix at only 1 of their 147 RIS peers -
https://stat.ripe.net/2001%3A4268%3A%3A#tabId=routing

What has AS15964 said to you about this?

Good luck
