how long does it take for FNB to do a refund and send a paid up letter for a paid up account

i have requested for my refund on the 27th February, i was promised to be refunded within 48 hours from the 28th February. Below is the trend of emails and still no one is willing to help me or reply to my emails. This type of service is really PATHETIC.

Good morning

As per our telephonic conversation last week Friday you promised me a refund within 48 hours, to date I haven’t received the refund and the paid up letter. Please advise on the progress.
