Kulula- extremely poor service!!!

Checked in online this morning at 06h00. Was able to get seat of my choice. Emailed boarding pass to my self. Went to check something on their website and found out that my seat allocation has been changed from the 2nd row to row no.11. This is the second time that this has happened to me with this airline. This is totally unacceptable and shoddy service!! Upon phoning the airline I was told that this can only be dealt with at the airport counter. No telephone number. !! Kulula affiliated to British airways? No ways,BA doesn't treat their customers like this. MY LAST FLIGHTS WITH KULULA THIS WEE**** THANK GOODNESS
