Depositor plus withdrawal

I opened a depositor plus account and need to transfer the balance to cheque account for a medical procedure I phone the call centre to ask why I can't transfer the complete amount without leaving the 1000r but was told I have to come into the bank and withdraw it , firstly how can I come into the bank when I am immobile and how can I withdraw, such a large amount and carry it with me .... Why do I have internet banking if I still have to come into the bank and may I ask how do I come to the bank when I can't walk ie the reason I need the money .<br> <br> This is disappointing as I cannot walk and have internet banking but cannot use it ,
