Bad service

I called Santam to cancel my cover on the 16th of May effective 1 June. Was advised the cancellation has been logged and my account will not be debited on the 25th. Come the 25th they debit. I call on the 27th now advised the cancellation was logged for July, they will correct and arrange a refund takes about 11 days. I call again today, the agent says again the cover is cancelled effective July then later corrects to June. But now the days to a refund starts counting from the 2nd of June not the day I called and it’s 14 working days. Agent proceeds to now say but call again on Thursday to follow up, but even on that day it won’t be the days that she is mentioning. I am being inconvenienced for an error made by them in the first place. I had to find means to pay my new insurer and now I have to wait until they see it fit to refund me? I need that money.
