Recycling account numbers and bad customer service

A service provider accidentally made a payment into a Standard Bank account that I closed. But because Standard Bank recycles account numbers (beware of this, because if you find yourself in my situation, some random person will end up with your money), I now have to bear the onus of going into a branch and going through the inconvenience of recovering my own money.

If that was not enough, the customer service call center agent just hung on me when I called to query the status of this payment.

Absolutely shoddy treatment from the Standard Bank call center agent and it is absolutely shocking that I stand to lose out on a significant amount of money because of a policy of recycling old account numbers! Truthfully the bad service at Standard Bank is the reason I closed my account in the first place!
