Sorry for this rant thread, but is anyone else having issues with Avios and Tierpoints from MH flights not posting with BAEC?

My BAEC number and status are always recorded correctly on the boarding pass, (lounge access and all emerald benefits are ok), after waiting the required 6-8 weeks for the points and Avios to post, have requested via official claim form on BA.com, then have to call them up to chase, scan and send in boarding passes, booking confirmations, so much hassle.

Only about 1 in 4 MH flights posts correctly, the others I need to claim (sometimes I never get anything - still waiting on a DXB-KUL in J from last October!), often I don't even bother claiming anymore.

I know this airline has been having other issues, but it's annoying, especially as I currently need to use them regularly and often pick them over star alliance options due to them being in One World.

Never had any issues with other partners, AA, QF, CX, JAL all always posted fine in the same time period.
