Easy way to combine them is to add the photos to a new Facebook page, select “Choose Layout” & frame grab the group photo (If you post the FB Page to yourself only, you’ll have have a permanent copy to access as required).
Contact a travel agent in your own country as many travel companies offer wedding packages around the world with everything taken care of for you and organised before you leave home.
That’s why I suggested contacting the customer services first & note the name of the person you speak to, then if a branch tells you something different you can refer them to that person in customer services. The staff in any branch will usually back down before having to confront anyone else.
Some banks / branches will allow you to transfer your account whilst others will tell you it’s not possible. I previously transferred a Kasikorn account to a branch in Bangkok from Pattaya with no problems.
Might be best it you contact you bank’s customer services who will advise you properly.
