Refund

Good day, I had a joined life policy with Absa which i requested to cancel more than a month ago. After numerous calls, emails, documents send, complaints made. The surrender amount has been paid but not the pro-rata amount, again i had to follow up made calls i was advised it will be escalated i spoke to Rezona Louw yesterday also been promised a call back & email but till now no respond no feedback. Again, i had to call this morning and was advised i will get feedback via email none received. What do i need to do to get this resolve its tiresome, frustrating & very disgusting!!!!!!!!
