Stay in your own country and try to improve it for the better of everyone. Your skills and experience are extremely unlikely to make you eligible to a long term visa in Thailand.
Look on the bright side, at least she got her passport back.
Baffles me why people pay someone in Thailand to get a UK visa, the agent can't bribe anybody and the applicant has to provide all of the evidence and attend VFS. I guess it's up to the individual if they want to throw money away and risk being scammed.
As others have stated, there's no need to transfer your account. If your reason is to avoid paying charges to access your money, use the mobile app instead to withdraw money or go into the bank with your card and passport. If the reason is to get your annual visa letter/statement etc then they can do this at a different branch to your home branch anyway. I opened my account in Hua Hin then moved to Sriracha and the bank provided the information required for immigration in less than 10 minutes earlier this year. Good luck.
Don't waste your money with an agent if you can't meet the requirements. They cannot bribe anyone to make it happen. Just save your money and come to Thailand more often.
