Over charge on my card!

Good morning as per our telephonic discussion about my bill.(Tracy).My bill came to R113.70 and an amount of R173.70 was put through on my card.(a cash tip was given.)Which as per your menu I had a special cheese burger,coffee & pepper sauce which I was charged R173.70 instead of R113.70 as per the bill.I discussed the matter with Tracy and she said that I will be reimbursed the over charge on my card.It was arranged that the R60.00 will be put in an envelope with my name Robert on it at the cash desk for collection.I will be sending my nephew(Tyrone) to collect it this afternoon.Your cooperation regarding this matter will greatly appreciated.Kind regards. To whom it may concern, Yesterday at about 11.05 am I went to your Spur at Ferndale mall Fern Creek Spur the copy of my email sent this morning to them is self explanatory.With my telephonic conversation with Tracy she was very helpful and agreed that I could collect my overcharge on my card,but when I spoke to her this morning she seemed reluctant.She also told me that I made a purchase of R45.00 which I did not.In fact I was given a bill for R113.70 and this morning she said it was R108.00. There seems to be something untoward going on there.All I want is the over charge on my card and as per our telephonic conversation agreed that I could collect it today,why the change? Your handling of this matter will be highly appreciated. I shall be collecting my over charge this morning as per our agreement(WithTracy).
