Exactly.
For example I have had an account with Krungsri for about 2 decades. First I was in the Pattaya Thai branch, but since that location was inconvenient for me I switched to the Sukhumvit branch.
In both branches there were no issues.
About 5 years ago the Sukhumvit branch switched to do only insurance, and I had to move to the one in Big C extra.
Since then every time I go in for anything there will be a fight because they make problems about everything. Next week I do my retirement extension, to which my Krungsri account is linked, and the moment I have the extension the account will be closed
