What should I do if my bank account is suspended in Thailand due to a name mismatch?

Further update regarding bank account. I have had an account with Bangkok bank for 3 years no problem....until 3 days ago. Logged in for online banking only to see account suspended...phone number and name don't match. Go into the bank to sort out, and to make it worse I couldn't find my bank book. I needed a receipt from the phone company to prove name and number belong to me and bank book...got neither !!

Anyway, bank staff very helpful and cooperative...cost 100 baht and we will make up new bank book...whilst we do that, go to AIS shop and change phone number in my name and get receipt. Did that , went back to the bank, signed a rain forest load of paper and job was done. ..and new bank book. Told it would be 7 days before reinstated....pleaded I need sooner because of bills to be paid, and 5 hours later back online. Brilliant service and relatively straightforward. Just saying....
