Poor form! Will Only Accommodate new clients!

We have held a partnership account with FNB for nearly 5 years now. We have recently become a PTY and need to start moving all our business over to the new Business account we opened with FNB for the PTY business. When we contacted the call centre this morning to find out if we can transfer our credit card and over draft facility to our new Business account. We were told that we cant do this, we will need to re-apply for credit card and overdraft all over again and we have to have 6 months of running bank account to do so!! Further more the agent tells us that they will only accommodate Bank account holders moving their business to FNB. Ie if they open a new business account with FNB and have an existing Credit card and overdraft facility with another Bank like Absa or Nedbank then they will do it without having to apply. So in other words if you are a new client they will accommodate you with no problem, but if you are an existing client, they couldnt be bothered. We now either have to look to moving to a new bank where hopefully they will try to accommodate us or we need to try and juggle between two bank accounts for 6 Months! And have to go through the application process again
