Debited my account and didnt provide ref number after my call

Hi. I was ****** twice in the space of 2 weeks, of which I had to replace 2 cards, both times. FNB debited my account of R140 for replacement fee, I queried this and the issue was resolved, I got my R140 back. But since then you have debited my account for a second time. I called the call center and spoke to Manny, she said I would receive my ref number via email.. I havent received anything and funds have not yet been reversed.
