FICA documents required within 10 days

I have been a Standard Bank customer for 12 years, no issues with my FICA documents ever. Now all of a sudden I get a sms (not even the courtesy to call me) stating that if I do not bring them FICA documents to a branch within 10 days, they will freeze my account. Due to work travel, it will be physically impossible for me to get to a branch within 10 days. Called the call centre, was told they will put me through to the FICA department, but after holding for 15 (FIFTEEN!!!!) minutes, I ended the call. I feel it is completely unreasonable to only give 10 days' notice, especially when you have to physically go into a branch!!! I think this is the end for me and Standard Bank!!!!! Good bye, will come into the branch, but it will be to close my accounts.
