price discrepancy

On 28 April 2015 I was at Mc Donald's in Cape Town, Adderley Street and bought a Big Mac burger only at R26.00. <br> <br> On 29 April 2015 at about 22:20 I went to Mc Donald's in Ottery, Cape Town and they wanted to charge me R27.50 for a Big Mac burger only. I then spoke to one of the staff members(gentleman), told him that I paid R26.00 for a Big Mac burger in Town. He then responded, stating that it can't be as all Mc Donald's have the same prices. I then bought a Mc Mac Burger meal instead. <br> <br> I am not happy with the price discrepancy, how can it be that two stores selling the same product at different prices. I feel that I was over charged wrongly.<br> <br> Can you please look into this matter urgently and rectify accordingly. <br> <br> Awaiting your speedy response and positive outcome. <br> <br> Thank you for attending to this matter.
