Standard bank is the pits

I app**** for the Payment holiday application with Standard bank. They sent an email that it was approved but the premium still got deducted. I have been calling them to request a refund, they promised me that they will refund within 3 to 4 business days. It has been 6 days and I still haven't received my refund. When I call to follow up, no one seems to know what the update is. I am frustrated as a Standard bank customer. They always do me dirty, this is not my first complaint. I am really tired of them honestly. I cannot call everyday to request an update on something that should not have happened in the first place. I have a new born baby that I need to feed, how will I do that if Standard bank does not want to refund me my money.
