Double decuction

I need someone to explain this to me please. On 1 Feb I went to Checkers and an amount of R346.87 was reserved for the payment. On my sms from FNB it clearly shows the funds were reserved for Checkers and my available funds reflected that it has been deducted. I did some more shopping and after my last transaction at McDonald's my available balance showed R5033. I wake up this morning with another deduction for Checkers showing my available balance for R4686. This has nothing to do with pending payments. If money has been reserved for Checkers already on 1 Feb, why is there another payment for the exact same amount making my available balance even less. So now you basically sitting with the reserved funds from 1 Feb and a deduction on 4 Feb. I have screenshot to prove my case and would appreciate one or the other to be reversed as I am not going to pay twice for the same payment. I've been trying for 2 hours ro explain this to your secure chat consultants to be told I am stupid and that I don't know what's going on. Then they proceed to cut me off and don't even talk any further. I have to explain it all over again to the next consultant. I've had enough now.
