Best bet is to check with the bank or ask your company to do the needful. 


After 2008 many sales staff at banks have been terminated, but it does not mean records are lost.


If you have the bank address and details, send them an email and they will respond. If you have so far not been contacted by the bank, most probably they have not raised a complaint with the authorities.  Also, if your previous company is bringing you back, they would have applied for your visa. If you have a new visa, means there are no issues raised.  You could have a problem only if you are applying for a credit card or loan.


All the best.
