Duplicate Deduction

I went to KFC Maitland on Sunday 5 July and my purchase totaled R 96.80. I entered my credit card pin on the machine and there was a paper jam or something to that effect and the receipt did not print. I had to wait about 15 minutes while the Manager, Fezekile tried to do a reprint and he clearly did not know HOW to do this. He eventually told me the transaction did not go through (after asking me if I had telephone banking which I do but because the transaction was under R 100 I don't receive an sms). He made me pay again and this morning I see on my bank statement that it came twice off my credit card. He took down my contact details and said he would call me if he was over when they cashed up and I have not received a call. I'm not impressed that the Manager is not trained to do a Reprint and makes me pay again.
