Business Banking - opening of accounts

I am very disappointed with the lack of service received with a simple task such as opening a subsidiary account on a business Enterprise portfolio. More than two months ago I have commenced the process event met with a representative but were sent from pillar to post with the call centre for the activation of the accounts. Communication is key but something this department clearly lacks in addition to the willingness to see a process through till finalised. Not sure why you are appointed a business banker of you need to resolve all these queries yourself as the banker does not have access or authority to escalate to various departments. Several complaints logged and still no resolution because it appears that you are only a number and just another email being received, wonder what the success rate on completion of queries and complaints are and or whether they are just left unattended as nobody makes an effort to pick up the phone and communicate with their clients as it appears
