When I was refused a bank account at Kasikorn I asked to speak to an English speaker. On the phone I asked how was I supposed to have money in the bank as required by immigration (400,000 baht) if I couldn't open a bank account. He thought about it and decided I could open a bank account and spoke to the local female that refused me an account. She lost face and did all she could to make things difficult for me but I eventually got the account and internet banking.
