Overcharged

Overcharged Went to woolworths on the 29th dec 18 to buy ice cream. The tin roof was on special which was R100 for 2. So i bought 2 tin roof ice cream and 2 woolies brand casturds and a pie so that should amount R157, to my surprise R211. 95 was reserved for payment and my phone was off and the till amount viewing thing was not working because the battery was off so when i got home to charge my phone i was charged more... I want my extra money i paid BACK!
